Hint: A = πr²
6 inches
Area = [?] inches²
Enter the number that
belongs in the green box.

Answer 1

28.26 inches^2

Explanation:

The area of a circle is given by the formula
`A = \pi r^2`.
We know that the diameter of the circle is 6 inches, therefore, its radius 3 inches (the radius is exactly one half of the circle's diameter).

Substituting into the formula

`A = \pi r^2 \\ \\\to A = \pi * 3^2 \\ \\\to A = \pi * 9 = 28.26`
