Question

A cylinder has a base area of 28.2 m2 and a height of 3.1 m. Estimate the volume of the cylinder.
A) 31 m3
B) 31 m2
C) 48 m2
D) 84 m3

Answer 1

Answer:

D) 84 m^3

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h

the base area is pi r^2

V = B h

We know the base area is 28.2 and the height is 3.1

V = 28.2 * 3.1

V =87.42

To estimate, round each value to the nearest whole number

V = 28 * 3

V =84

Answer 2

C because if you do 28.2 divide by 3.1 it’s 48
