WebExample: Find the circumference of the circle with a diameter of 8 inches. Solution: Answer: The circumference of the circle is 8 π ≈ 25.163 inches. Example: Find the … 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.
