Exercise 11 Page 595

Recall the formula for the volume of a cylinder, V = π r^2 h.

About 2771.0 yd^3

Practice makes perfect

Consider the given a cylinder. The diameter is 21 yards and the height is 8 yards.

The volume of a cylinder with the radius r and height h can be calculated by the following formula. V=π r^2 h The diameter d is 21. We can find the radius by dividing d by 2.

r = d/2

Substitute

d= 21

r = 21/2

CalcQuot

Calculate quotient

r = 10.5

Now, we can substitute them into the formula and calculate V.

V = π r^2 h

SubstituteII

r= 10.5, h= 8

V = π ( 10.5)^2( 8)
