Question

The area of a circle is 50.24 square centimeters. What is the circle's diameter?

Use 3.14 for r.

Answer 1

8 Square Centimeters

Explanation:

The formula for area is A = πr²

Filling in the area and Pi, we get 50.24 = 3.14(r)²

Divide both sides by 3.14, and we get 16 = r²

Square root of 16 is 4, so 4 = r

Now, we have the radius of the circle. The formula for diameter is d = 2r

4 · 2 = 8

So the diameter is 8 cm² (8 Square Centimeters)
