Question

Find the exact and the approximate volume of the cylinder. Round your approximation to the nearest hundredth. Show all work.

Answer 1

V=hieght times pi times radius^2
diameter/2=radius
12/2=6=radius
height=10



v=10*pi*6^2
v=10*pi*36
V=360pi
using pi=3.141592
V=1130.97312
round
V=1130.97 cubic centimeters

Answer 2

V=hpr^2

V=10p(12/2)^2

V=360p cm^3  exact

V=1131 cm^3  (to the nearest tenth of a cubic centimeter)
