Question

The diameter of a circle is 4 ft. Find its area in terms of piπ.

Answer 1

[AI-generated answer — Bot GPT 3.5]

The formula for the area of a circle is A = πr^2, where r is the radius of the circle.

Since the diameter of the circle is 4 ft, the radius is half of the diameter, which is 4/2 = 2 ft.

Plugging in the radius into the formula, we get:

A = π(2)^2
A = π(4)
A = 4π

Therefore, the area of the circle is 4π square feet.
