The formula to figure out the circumference of a circle is C=2(pi)r. So with a circle that has a radius of 40 inches, you can set up the formula like: C=2(pi)40. To figure this out on a calculator, multiply 2 with pi and then multiply that answer with 40. If you do not have a pi symbol on your calculator you can multiply 2 with 3.14159 then multiply that answer with 40.
A circle with a radius of 8 inches has a circumference of 50.27 inches.
The radius of a circle with a circumference of 232.4 inches is 37 inches.
Circumference = 2 x pi x radius = 31.4159
c = 22"
That will depend on the length of the radius which has not been given but in general the circumference of a circle = 2*pi*radius or diameter*pi
A circle with a radius of 8 inches has a circumference of 50.27 inches.
The radius of a circle with a circumference of 232.4 inches is 37 inches.
Circumference = 2 x pi x radius = 31.4159
The approximate radius is five (5) inches.
radius = 20/(2*pi) = 3.183098862 inches
The circumference of a circle that has a radius of 5 inches is 10 X pi or approximatly 31.415926535897932384626433832795. If you know the radius you can find the circumference by multiplying it by 2(pi)
C = 25.13 inches.
c = 22"
To find the radius of a circle with a given circumference, you can use the formula: circumference = 2 * π * radius. Given that the circumference is 26 inches, you can plug this value into the formula and solve for the radius. Dividing the circumference by 2π gives you the radius of the circle, which in this case is approximately 4.14 inches.
That will depend on the length of the radius which has not been given but in general the circumference of a circle = 2*pi*radius or diameter*pi
Circumference = 31.4 inches, approx. Area = 78.5 square inches, approx.
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
