Question

The volume of a cylinder is 480 cm. The height of the cylinder is 30 cm. What is the radius of the

Answer 1

Answer:

Step-by-step explanation:

Given

Volume of Cylinder (V)= 480 cm

height (h) = 30 cm

radius (r) = ?

WE KNOW THAT WE HAVE FORMULA

Volume (V) = $\pi r^{2} h$

           480 = 3.14 * r^2 *30

            480 = 94.2 r^2

             480/94.2 = r^2

               r^2 = 5.1

                 r =$\sqrt{5.1}$

Therefore r = 2.3 cm
