## anonymous 3 years ago how do you do the volume of a cylinder?

1. anonymous

A cylindrical barrel of oil has a height of 1.5m and a diameter of 0.6m. Calculate its total capacity.

2. anonymous

v=pi x r^2 x h

3. anonymous

v= 3.14 x 0.3^2 x 1.5

Volume of any 'prism' is Area of base * height. Base is the area of circle which is pi*r^2. So volume is pi*r^2*h radius is half of diameter so just halve your value.

$\Huge{\color{red}{ \pi r^2 h}}$

so i do pi x r2

7. anonymous

yes then times height
