Question

The diameter of a circle is 0.82 inches. What is the approximate area of the circle?

Answer 1

0.527834

Explanation:

Diameter = 2 x radius

Area of circle formula: πr²

0.82/2 gives us the radius.

The radius is 0.41 so let's square that.

0.41²= 0.1681

0.527834

Answer 2

Diameter = 2 x radius

Area of circle formula: πr²

0.82/2 gives us the radius.

The radius is 0.41 so let's square that.

0.41²= 0.1681

Your answer is 0.1681π OR approximately 0.527834*

(*since 0.1681 times 3.14 is approximately 0.527834)
