Find the circumference of the circle. Round your answer to the nearest hundredth. Use 3.14 or 227 for π.
theres a picture of a circle with the radius of 21 cm
C = 2πr
To find the circumference of a circle, you can use the formula C = 2πr, where C represents the circumference and r represents the radius of the circle. In this case, the radius is given as 21 cm.
Using the formula and substituting the value of the radius, we have C = 2 * π * r = 2 * 3.14 * 21 ≈ 131.88 cm.
Rounding this answer to the nearest hundredth, the circumference of the circle is approximately 131.88 cm.
