Question

A cylinder has a volume of 400 cubic feet. If the height of the cylinder is 25 feet, what is the radius of the cylinder? Use 3. 14 for π and round to the nearest hundredth.

Answer 1

The radius of the cylinder will be  $r=2.25ft$

What will be the radius of the cylinder?

It is given that

$Volume of the cylinder = 400 ft^{3}$

$height of the cylinder= 25 ft^{3}$

Now we know that

$Volume of the cylinder = \pi r^{2} h$

putting values in the formula

$400= \pi \times r^{2} \times25$

$r= \dfrac{4}{\sqrt{3.14} }$

$r=2.25 ft$

Thus the radius of the cylinder will be  $r=2.25ft$
