The surface area of a cone with radius of 4 m and slant height of 5 m is 36π m²
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
The surface area of a cone with radius (r) and slant height (l) is:
S.A = πr(r + l)
Given that r = 4, l = 5, hence:
S.A = π(4)(4 + 5) = 36π m²
The surface area of a cone with radius of 4 m and slant height of 5 m is 36π m²

what is 20/4 - 8 please help
Answers
Answer is: -3
Answer:
-3
Step-by-step explanation:
Multiply and divide {left to right}:
20/4 = 5
Add and subtract {left to right}:
5 - 8 = -3
{Negative + Positive = Negative}
Fraction:
The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
LCD(20/4, 8/1) = 4
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
[tex](\frac{20}{4} *\frac{1}{1} )-\frac{8}{1} *\frac{4}{4} )=[?][/tex]
Complete the multiplication and the equation becomes
[tex]\frac{20}{4} -\frac{32}{4} =[?][/tex]
The two fractions now have like denominators so you can subtract the numerators.
Then:
[tex]\frac{20-32}{4} = \frac{-12}{4}[/tex]
Since -12 divided by 4 equals -3 then,
[tex]\frac{-12}{4}=-3[/tex]
Therefore, -3 is the correct Answer or Fraction form = -1/3

Answer:
[tex]V = 97.911in^3[/tex]
Step-by-step explanation:
Given
Shapes: Cube and Cone
Required
Determine the volume
First we calculate the volume of the cube
[tex]V_1 = l^3[/tex]
Where
l = side length = 5.1
[tex]V_1 = 5.1^3[/tex]
[tex]V_1 = 132.651[/tex]
Next, calculate the volume of the cone using:
[tex]V_2 = \frac{\pi r^2h}{3}[/tex]
Where
h = 5.1
[tex]r = \frac{1}{2} * Diameter[/tex]
[tex]r = \frac{1}{2} * 5.1[/tex]
[tex]r = 2.55[/tex]
So, we have:
[tex]V_2 = \frac{\pi r^2h}{3}[/tex]
[tex]V_2 = \frac{\pi * 2.55^2 * 5.1}{3}[/tex]
[tex]V_2 = \frac{22 * 2.55^2 * 5.1}{7*3}[/tex]
[tex]V_2 = \frac{729.5805}{21}[/tex]
[tex]V_2 = 34.74[/tex]
The volume of the figure is:
[tex]V=V_1 - V_2[/tex]
[tex]V_1 = 132.651[/tex]
[tex]V = 132.651 - 34.74[/tex]
[tex]V = 97.911in^3[/tex]

How many quarts will you get if you mix 5 gallons 5 quarts and 6 pints
Answers
Answer:
28
Step-by-step explanation:
There are 4 quarts in a gallon, and since we have 5 gallons that gives us 20 quarts. Then we add the 5 quarts to give us 25 quarts. Finally, there are 2 pints in quart, so that gives us 3 quarts. Add those last three quarts and we get 28 quarts in all.
Total quarts when you mix 5 gallons 5 quarts and 6 pints is, 28 quarts
We have to given that,
To find total quarts if you mix 5 gallons 5 quarts and 6 pints.
Since, 1 gallon = 4 quarts
Hence, 5 gallons = 5 x 4 = 20 quarts
And, 1 pints = 1/2 gallons
Hence, 6 pints = 6/2 gallons
= 3 gallons
So, Total quarts when you mix 5 gallons 5 quarts and 6 pints is,
20 + 5 + 3
28 quarts
Therefore, Total quarts when you mix 5 gallons 5 quarts and 6 pints is,
28 quarts.

beyond the included 800 minutes in the
plan. How much will it cost Tom if he used his cell phone for 850 minutes in one month?
Answers
Answer:
88.99
Step-by-step explanation:
his plan includes 800 minutes for 79.99, all we need to do is calculate the cost of the extra 50mins he used and add it to 79.99. this is ((850-800)*0.18) +79.99 and this is equal to 88.99
$0.18 X 50 minutes over the included 800
Total = $79.99 + $9 = $88.99
