Answer:

615.44

Step-by-step explanation:

If the diameter is 28, that means the radius is 14.

The formula for the area of a circle is pi x radius to the power of 2. So, 14 to the power of 2 (or 14 x 14) equals 196. 196 x 3.14 (pi) = 615.44

The estimated area of the circle is about 615.44 cm² or 616 cm², depending on which value you use for π.

Suppose the circle has radius of 'r' units, then, its area is given as:

[tex]A = \pi \times r^2[/tex] sq. units

Since radius of a circle is half of its diameter, so if diameter is of 'd' length, then r= d/2, thus, area can be rewritten as:

[tex]\pi \times (\dfrac{d}{2})^2[/tex] sq. units

We are given that;

Diameter=28cm

Now,

In this case, the diameter of the circle is 28 cm, so the radius is half of that:

r = 28 / 2 = 14 cm

Plugging this value into the formula, we get:

A = π × 14²

Now we can use either 3.14 or 22/7 for π. Let’s use both and compare:

A ≈ 3.14 × 14² ≈ 3.14 × 196 ≈ 615.44 cm²

Or

A ≈ (22/7) × 14² ≈ (22/7) × 196 ≈ (4312/7) cm² ≈ 616 cm²

Therefore, by the area of circle the answer will be 615.44 cm² or 616 cm², depending on which value you use for π.

Step-by-step explanation:

Hey there!

Perpendicular lines have slopes that are opposite reciprocals. This means we take a number, flop it over, and change its sign.

In this case, the slope is 1/6.

First, flop it over:

6/1 (or just 6)

Then, change its sign:

-6

Now, the line passes through the point (0, 5)

The reason 5 is highlighted is because it's the y-intercept of 5.

So we have the Slope & the Intercept.

See what I mean? Yeah! We can write the line's equation in Slope-Intercept Form (y=mx+b)

In this formula, m stands for the slope, and b stands for the y-intercept.

In this case, -6 is the slope, and 5 is the y-intercept.

Hence, the equation is

[tex]\boxed{\boxed{\bold{y=-6x+5}}}[/tex]

Hope everything is clear.

The slope of the line that passes through the points (1, -2) and (3, -5) is -3/2.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

We need to find slope of line passing through the points (1, -2) and (3, -5)

m= -5-(-2)/3-1

=-5+2/2

=-3/2

Hence, the slope of the line that passes through the points (1, -2) and (3, -5) is -3/2.

Answer:

3300 m²

Step-by-step explanation:

Area of a triangle = 1/2 x base x height

⇒ area of one triangle = 1/2 x 30 x 40 = 600 m²

Area of a square = side length x side length

⇒ area of the square = 30 x 30 = 900 m²

Surface area of square-base pyramid = area of 4 triangles + area of square

⇒ SA = 4 × 600 + 900 = 2400 + 900 = 3300 m²

x = [tex]\sqrt{15}[/tex]

Step-by-step explanation:

Since 2 sides are equal then triangle is isosceles and the segment from the vertex is a perpendicular bisector.

Th triangle is divided into 2 right triangles with legs x and 7 and hypotenuse 8

Using Pythagoras' identity, then

x² + 7² = 8²

x² + 49 = 64 ( subtract 49 from both sides )

x² = 15 ( take square root of both sides )

x = [tex]\sqrt{15}[/tex]

Given:

6 gallons of light green paint uses [tex]\dfrac{3}{8}[/tex] gallon of white paint.

Liam has [tex]\dfrac{9}{16}[/tex] gallon of white paint.

To find:

Whether Liam have enough white paint to make 8 gallons of light green paint.

Solution:

Here, 6 gallons of light green uses [tex]\dfrac{3}{8}[/tex] gallon of white paint.

So, the white paint for 1 gallon of light green [tex]=\dfrac{\dfrac{3}{8}}{6}[/tex]

                                                                          [tex]=dfrac{3}{8\times 6}[/tex]

                                                                          [tex]=\dfrac{3}{48}[/tex]

                                                                          [tex]=\dfrac{1}{16}[/tex]

It means, 1 gallons of light green uses [tex]\dfrac{1}{16}[/tex] gallon of white paint.

White paint for 8 gallon of light green [tex]=8\times \dfrac{1}{16}[/tex]

                                                               [tex]=\dfrac{8}{16}[/tex]

She has [tex]\dfrac{9}{16}[/tex] gallon of white paint, which is greater than  [tex]=\dfrac{8}{16}[/tex] gallons.

Therefore, Liam have enough white paint to make 8 gallons of light green paint.

If Liam has 9/16 gallon, he has enough white paint to make 8 gallons of light green paint

Given that 6 gallons of light green paint use 3/8 gallon of white paint, this can be expressed as:

3/8 gallons of white paint = 6 gallons of light green

We are to determine if 9/16 gallons will be enough to make 8 gallons of light green paint. This can be expressed as

9/16 gallons of white paint = x

Divide both expressions

3/8 * 16/9 = 6/x

2/3 = 6/x

Cross multiply

2x = 3 * 6

2x = 18

x = 18/2

x = 9

This shows that if Liam has 9/16 gallon, he has enough white paint to make 8 gallons of light green paint

The area of mathematics that deals with particular angles' functions and how to use those functions in calculations. There are six popular trigonometric functions for an angle. Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant are their respective names and acronyms (csc).

Given:

H= 25

P = 24

Now, Base, B= √H² - P²

B= √25² - 24²

B= √625- 576

B= 7

Now, tan [tex]\theta[/tex] = P/ B

                  = 24/ 7

Hence, the value for the tan [tex]\theta[/tex]  is 24/7.
