Question

A circle’s circumference is approximately 76 cm.

Estimate the radius of the circle.



Use 3.14 for .

Round your answer to the nearest whole number.

Answer 1

Answer: Area= 459.73cm^2

Step-by-step explanation: Circumference of a circle is 2πr

76=2×3.14×r

r= 76÷(6×3.14)

r=12.10

Area of a circle= πr^2

Area= 3.14×(12.10)^2

Area= 456.73cm^2
