the formula is pi times r squared
pi = 3.14
r = 3
3 squared = 9 so its 3.14 times 9
Multiply the diameter by Pi (about 3.1416). The result is the circumference:3 x 3.1416 = 9.4248 inches circumference
The circumference of a circle when the radius is 3 inches is: 18.8 inches (r x 2 x Pi = circumference)
A circle with a radius of 3 inches has a circumference of 18.8 inches
A circle with a radius of 8 inches has a circumference of 50.27 inches.
Circumference: 29*pi = 91.106 inches to 3 decimal places
Multiply the diameter by Pi (about 3.1416). The result is the circumference:3 x 3.1416 = 9.4248 inches circumference
The circumference of a circle with a diameter of 3 inches is 9.425 inches.
A circumference of 9.42 inches.
The circumference of a cirlce that has a diameter of 3 inches would be about 9.42 inches
The circumference of a circle when the radius is 3 inches is: 18.8 inches (r x 2 x Pi = circumference)
a circle with circumference of 25.56 inches.
3 inches x 3.1416 = 9.42 inches
A circle with a radius of 3 inches has a circumference of 18.8 inches
A circle with a radius of 8 inches has a circumference of 50.27 inches.
circumference = 2*pi*11 = 69.115 inches to 3 dp
Circumference: 29*pi = 91.106 inches to 3 decimal places
The diameter of a 3-inch circumference is: 0.954 inches.
