Exercise 34 Page 638

The given solid is a cylinder with a radius of 2 inches and a height of 25 inches. To calculate the volume of a cylinder with radius r and height h, we can use the following formula. V=π r^2 h Since we are given both the radius and height of the cylinder, we can substitute them into the formula and calculate V.

V=π r^2 h

SubstituteII

r= 2, h= 25

V=π ( 2)^2 ( 25)
