Question

What is the approximate volume of a cylinder with a diameter of 10 meters and a height of 5 meters? Use 3.14 for pi. A. 392.5 m3 B. 1570 m3 C. 314 m3 D. 130.8 m3

Answer 1

For cylinder
d=10m
So r=5m
h=5m
volume=pi×r^2×h
=3.14×5×5×5
=3.14×125
=392.5m^3
So option a is correct.

Answer 2

= (3.14)(20/2)²(5)
= 15.7(10)²
= 15.7(100)
= 1,570

Answer: D. 1,570 cubic meters
