Answer: 20.28 cm^2
Explanation:
First find the area of the square!
7 x 2 = 14
then find the area of the circle!
We know that the DIAMETER of the circle is 4 because the total length of the square is 7 cm and there are 3cm of length on the sides of the circle
so 7-3 = 4
Then to find the area of a circle you need to use this formula:
r = radius
A = 3.14r^2
3.14(2)^2 = 12.57
Then you need to divide it by TWO because its a half circle!
12.57 / 2 = 6.285
14 + 6.285 = 20.28 cm^2
I hope this helped!

Cole wants to buy carpet to cover his whole living room, except for the tiled floor. The tiled floor is 4 5 6 ft by 2 1 3 ft. Find the area the carpet needs to cover. Solve on paper. Then check your work on Zearn. 711 1 3 tiled floor The carpet needs to cover ft2.
Answer:
[tex]Area = 49\frac{25}{36}[/tex]
Step-by-step explanation:
Given
Tile
[tex]Length = 4\frac{5}{6}[/tex]
[tex]Width = 2\frac{1}{3}[/tex]
See attachment for dimension of the floor
Required
Determine the area covered by the carpet
From the attachment, the dimension of the floor is:
[tex]Length = 12\frac{1}{4}[/tex]
[tex]Width = 5[/tex]
Calculate Area
[tex]Area = Length * Width[/tex]
[tex]Area = 12\frac{1}{4} * 5[/tex]
[tex]Area = 61\frac{1}{4}[/tex]
The area of the tiles is:
[tex]Area = 4\frac{5}{6} * 2\frac{1}{3}[/tex]
[tex]Area = \frac{29}{6} * \frac{7}{3}[/tex]
[tex]Area = \frac{203}{18}[/tex]
[tex]Area = 11\frac{5}{18}[/tex]
So, the carpet area is:
[tex]Area = Floor\ Area - Tile\ Area[/tex]
[tex]Area = 61\frac{1}{4} - 11\frac{5}{18}[/tex]
To improper number
[tex]Area = \frac{245}{4} - \frac{208}{18}[/tex]
Take LCM
[tex]Area = \frac{2205 - 416}{36}[/tex]
[tex]Area = \frac{1789}{36}[/tex]
[tex]Area = 49\frac{25}{36}[/tex]

ASAP!: can anyone solve three times the difference of Federico age and 4 increased by 7 is greater than 37 what are possible values of Federico age?
Answer:
Federcio's age possible values are those that are greater than 14 i.e 15, 16, 17 and so on
Step-by-step explanation:
Let Federico's age = x
Three times the difference of Federico’s age, and 4 means:
3(x - 4)
Increased by 7:
3(x - 4) + 7
Is greater than 37:
3(x - 4) + 7 > 37
Solving the inequality:
3x - 12 + 7 > 37
3x - 5 > 37
3x > 37 + 5
3x > 42
x >42/3
x > 14
Federcio's age possible values are those that are greater than 14
What is the surface area of the pyramid formed from the net shown here? The triangles are equilateral, and each triangle has a height of 5.2 centimeters. Write your answer rounded to one decimal point and with the correct unit. 6.3 Incorrect. The surface area of an equilateral triangular pyramid is given by the formula surface area = 2bh. The surface area of this equilateral triangular pyramid is 2bh = 2 × 6 cm × 5.2 cm = 62.4 square centimeters. Enter the correct answer. the net of an equilateral triangular pyramid
Answer:
the surface area of the pyramid is 62.4 square centimeters
Step-by-step explanation:
The computation of the surface area of the pyramid is shown below:
As we know that
The surface area = 2bh
= 2 × 6 cm × 5.2 cm
= 62.4 square centimeters
Hence, the surface area of the pyramid is 62.4 square centimeters
The roof of a clock tower is a square pyramid. Each side of the base is 16ft long. The slant height is 22ft. What is the lateral area of the roof?
Answer:
The area of the pyramid is 703.97 ft²
Step-by-step explanation:
The lateral area of a right square pyramid is given as;
[tex]A_l =a \sqrt{a^2 + 4h^2}[/tex]
where;
a is base length
h is the vertical height of the pyramid
The vertical height of the pyramid is calculated as follows;
the vertical height passes through the center of the base.
half of the base = 8 ft
the slant height = hypotenuse side of the right triangle = 22 ft
Thus; h² = 22² - 8²
h² = 420
h = √420
h = 20.493 ft
The area of the pyramid is calculated as;
[tex]A_l =a \sqrt{a^2 + 4h^2}\\\\A_l =16\sqrt{16^2 + 4(20.493)^2} \\\\A_l = 703.97 \ ft^2[/tex]
Therefore, the area of the pyramid is 703.97 ft²

The youth soccer team is fundraising by washing cars. They paid $84.55 for supplies. If
they charge $8.00 per wash, how many cars must be washed to profit at least $300.00 dollars?
Answer:
The soccer team must wash 49 cars in order to gain at least $300.
Step-by-step explanation:
The soccer team started out by paying $84.55. They charge $8 per car wash. So let's say how many cars they washed was x. They need to gain at least $300 dollars. If we put this in an equation it looks like this (we are solving for x):
8x - 84.55 >or= 300
To find x we have to do the following steps:
8x - 84.55 >= 300
+ 84.55 + 84.55
8x >= 384.55
/8 /8
x >= 48
Now we have to make sure that this is correct:
8 * 48 - 84.55 = ?
384 - 84.55 = 299.45
Since 299.45 is less than 300, x must be greater than 48, but since 299.45 is so close to 300, my educated guess would be that x=49.
8 * 49 - 84.55 = ?
392 - 84.55 = 307.45
Since 307.45 is greater than 300, x=49. So we can conclude that they must wash 49 cars to profit at least $300.

Gavin is measuring strips of craft wood for a geometry project. He needs 42 feet of wood. He has 11 23 yards. How many more yards of wood does he need?
Answer:
2 1/3 yards
Step-by-step explanation:
Total length of wood needed = 42 feet
Convert feet to yards
1 feet = 0.333333 yards
42 feet = 14 yards
He has 11 2/3 yards.
How many more yards of wood does he need?
= 14 yards - 11 2/3 yards
= 14 - 35/3
= (42-35)/3
= 7/3
= 2 1/3 yards
He needs 2 1/3 yards more yards of wood

If you look carefully at these two shapes, you will notice that the first one is just an upside-down version of the second one. The question also states that these two shapes are congruent, meaning that they are the exact same shape. To figure out the measure of angle U, you must simply flip the first shape right-side up. You can either do this in your mind or on paper. To do it on paper, just draw the shape then rotate the paper until the shape looks identical to the other shape. Once you do this, you will see that angle G is the same as angle U. Their angle measurements be the same as a result.
I hope this makes sense. Please let me know if there is any other way I can help you. Good luck!
