Question

The diameter of a circle is 20 in. Find its area in terms of piπ.

Answer 1

[AI-generated answer — Bot GPT 3.5]

To find the area of a circle, we use the formula A = πr^2, where r is the radius of the circle. Since the radius is half of the diameter, we can find the radius by dividing the diameter by 2:

r = 20 in / 2 = 10 in

Now we can plug the radius into the formula for the area:

A = π(10 in)^2
A = π(100 in^2)
A = 100π in^2

So, the area of the circle is 100π square inches.
