Question

at is the volume, in cubic meters, of a cylinder with a height of 4 meters and a base radius of 7 meters, to the nearest tenths place?

Answer 1

V = volume of cylinder, r = radius, h = height

In this case, r = 7 and h = 4.

V = pi*r^2*h

V = pi*7^2*4

V = pi*49*4

V = pi*196

V = 196pi <<-- exact volume in terms of pi

V = 196*3.14159

V = 615.75 <<--- approximate volume

V = 615.8 <<--- rounding to 1 decimal place

Final Answer: 615.8 cubic meters
