Solve for the circumference by using the formula: c=2πr
a) Determine the circumference by rounding to the nearest hundredths place (use π in your calculator) =⚫️ 16in
To find the circumference (c) of a circle with a radius (r), you use the formula c = 2πr.
Given that the circumference is 16 inches, you can use the formula to solve for the radius.
16 = 2πr
Divide both sides of the equation by 2π:
16 / 2π = r
Using a calculator to approximate π to the nearest hundredths:
16 / (2 * 3.14) ≈ r
16 / 6.28 ≈ r
2.55 ≈ r
Therefore, the radius is approximately 2.55 inches.
