Question

Solve the following given problem

Answer 1

The radius is 3.5cm

Explanation:

Given

`V = 192.5cm^3`

`h = 5cm`

Required

The volume (V)

The volume of the vase is:

`V = \pi r^2h`

So, we have:

`192.5 = 22/7 * r^2 * 5`

Divide by 5

`38.5 = 22/7 * r^2`

Multiply by 7/22

`12.25= r^2`

Take positive square roots

`r = 3.5`
