A lamp shade has a radius of 9 inches. What is the circumference of the top of the shade? Use 3.14 to approximate pi. Round your answer to the nearest whole number.
C=2×3.14×9 C≈56.52 inches, now we just need to round it up to get 57 inches. As a result, the circumference of the top of the shade is 57 inches. Hope it help!
