Diego is told that the circumference of a circle is 3π inches. How can he find the area of the circle? Fill in the blanks to help Diego calculate the area of the circle. Leave the final answer for area in terms of pi, and enter your numbers in decimal form.
Because the circumference of the circle is 3π inches, the radius of the circle is ____ inches. This means that the area of the circle is ____ square inches.
Because the circumference of the circle is 3π inches, the radius of the circle is 3π / (2π) = 1.5 inches. This means that the area of the circle is π * (1.5)^2 = 2.25π square inches.
Therefore, the area of the circle is 2.25π square inches or approximately 7.07 square inches.
