For the circle below with diameter 16 in, solve for the circumference by using the formula. C=2pir
A Determine the circumference by rounding to the nearest hundredths place(use pi in your calculator
Circumference = 2 * pi * r
r = 16 in / 2 = 8 in
Circumference = 2 * pi * 8
Circumference = 16 * pi
Circumference ≈ 50.27 in
Therefore, the circumference of the circle is approximately 50.27 inches.
