A circle with a radius of 3.3 units has a circumference of 20.73 units.
The radius of a circle whose circumference is 40pi is 20 units.
Circumference of circle: 2*pi*6 = 37.699 units to three decimal places
circumference = 2*pi*5.8 = 36.442 units of measurement to 3 dp
The circumference of a circle whose radius is 6 inches is: 37.7 inches.
pi = 3.1416 ( a constant) Circumference = 2 * pi * radius, so radius = circumference / (2 * pi) So radius = 28 / ( 2 * 3.1416 ) = 4.456 units
The radius of a circle whose circumference is 36 pi (113.1) is: 18 (circumference divided by Pi divided by 2 = radius)
The radius and diameter of a circle whose circumference is 25.12 are:r = 4d = 8
A circle with a radius of 21 meters has a circumference of 131.95 meters.
The circumference of a circle whose radius is 12.2m is: about 76.65m (C = r x 2 x Pi).
A circle with a diameter of 2.5 units has a circumference of 7.9 units.
Multiply the radius by 2xpi.
