The circumference of a circle with a diameter of 39 centimeters is about 122.5 cm (C = d x Pi)

Circumference equals pi times diameter. Therefore you divide 39 by pi and get about 12.41

39 inches / pi = 12.4 inches

First we have to find the radius: pi*radius2 = 120 sq ins Divide both sides by pi and then square root both sides: radius = 6.180387232 inches circumference = 2*pi*radius circumference = 38.83251825 or 39 inches to the nearest inch.

39 square centimeters is 6.04 square inches.

The diameter will be 12.41408556 inches

Recall that the circumference of a circle is: C = πd where d is the diamater Let d = 39 m. Then: C = 39π m

Divide 39 by pi to find the diameter of circle 1 and then subtract four inches from your answer to give the diameter of circle 2.Circle 1 = 39/pi = 12.41408556 inchesCircle 2 = 12.41408556 - 4 = 8.41408556 inches

Estimate: 3*40 = 120 inches Actual: pi*39 = 122.5 inches to one decimal place
