WebSolution: Estimate 3 × 8 2 = 3 × 64 = 192. The area of the circle, A = π r 2. = 22 7 × 8 2 (Substitute 22 7 for π and 8 for ‘r’) = 22 7 × 64 (Evaluate 8 2 and divide out the common factor) = 201.14 (Multiply) The area is about 201 square centimeters. It’s reasonable compared to the estimated value of 192 ∼ 201.14. WebA circle has a radius 8 cm. Calculate its diameter, area and circumference.

The circumference of a circle can be found by multiplying pi ( π = 3.14 ) by the diameter of the circle. If a circle has a diameter of 4, its circumference is 3.14*4=12.56. If you know the radius, the diameter is twice as large. 1 comment
