Question

What is the volume of right circular cylinder hows diameter is 6 and height is 7

Answer 1

V=197.92

Explanation:

Diameter (d) =6

Height (h) =7

Solution:

V=π(d/2)^2

H=π(6/2)^2 . 7=197.92034

Answer 2

if it has a diameter of 6, that means its radius is half that or 3.

`\textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=3\\ h=7 \end{cases}\implies V=\pi (3)^2(7)\implies V\approx 197.92`
