The radius of a circle with a circumference of 232.4 inches is 37 inches.
Oh, what a lovely question! To find the circumference of a circle with an area of 144π square inches, first we need to find the radius using the formula for the area of a circle, A = πr^2. Once we find the radius, we can calculate the circumference using the formula C = 2πr. Remember, there are no mistakes, just happy little accidents in math!
the equation to find circumference is C=2*pi*radius so when you have a radius of 18 inches, C=113.097
First we have to find the radius: 2*pi*radius = 18*pi Divide both sides by 2*pi to find the radius: radius = 9 inches Area of a circle = pi*radius2 Area = pi*92 = 81pi or 254.4690049 square inches
Use: 2*pi*radius = circumference
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.
Circumference = 2*pi*radius or pi*diameter Circumference = 36pi inches
diameter = circumference/pi = 37/3.1416 = 11.8 inches; radius = 1/2 diameter = 5.9 inches; radius = circumference/(2pi) = 5.9 inches = 37/6.2832 = 5.9 inches
The area of a circle is (pi x radius squared) A = πr2 The circumference is (pi x diameter) C = π (2r) So if you have the circumference, the area is the circumference squared, divided by 4pi (about 12.566). A = C2/4π Example: A circle with a diameter of 6 inches has a radius of 3 inches Area A = pi (32) or about 28.27 square inches Circumference C = pi (6) or about 18.85 inches Using C2/4pi, the area is 18.85 x 18.85 / 12.566 = about 28.27 square inches
