Question

Find the circumference and the area of a circle with diameter equal to 8.6 inches. Use 3.14 for pi

Answer 1

Answer: Circumference of circle = 27.004 inches

              Area of circle = 58.0586 inches²

Step-by-step explanation:

Diameter of circle = 8.6 inches

Pi ($\pi$) = 3.14

Circumference of circle (With diameter) = $\pi$d ($\pi$×diameter)

                                                                = 3.14 × 8.6

                                                                = 27.004 inches

Area of circle (With diameter) = $\pi$$d^{2}$/4

                                                 = 3.14 × 8.6 × 8.6 / 4

                                                 = 3.14 × 73.96 / 4

                                                 = 58.0586 inches²
