Question

Determine the radius of a cylinder with a volume of 163 ft cubed with a height of 4 ft​

Answer 1

The volume of a cylinder is given by the product of its base area (i.e. the area of a circle) and its height:

$V = \pi r^2\cdot h$

Solving for r, we have

$r=\sqrt{\dfrac{V}{h\pi}}$

Plugging the numbers, we have

$r=\sqrt{\dfrac{163}{4\pi}} \approx 3.6$
