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.
Lisa [10]

The radius of the cylinder will be  r=2.25ft

<h3>What will be the radius of the cylinder?</h3>

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
