Question

The radius of the water well is 2r inches. Find the area of the water well.

Answer 1

The area of the water well is $4\pi r^2$

How to determine the area?

The radius is given as:

Radius, R = 2r

The area of the water well is calculated using:

$A = \pi R^2$

This gives

$A = \pi (2r)^2$

Evaluate the expression

$A = 4\pi r^2$

Hence, the area of the water well is $4\pi r^2$
