Question

What is the volume of this cylinder use 3.14 for pie
72
200.96
204.53
226.08

Answer 1

The formula of a volume of a cylinder:

$V=\pi r^2H$

r - radius

H - height

W have r = 3cm and H = 8cm. Substitute:

$V=\pi(3)^2(8)=\pi(9)(8)=72\pi\ cm^3$

$\pi\approx3.14\to V=72(3.14)=226.08\ cm^3$

Answer: 226.08 cm³.
