How do you find the circumference of a circle using the radius?
Circumference = 2*pi*radius So the radius = circumference/2*pi
Is the radius one fourth of the circumference?
No. It is circumference/(2*pi)No. It is circumference/(2*pi)No. It is circumference/(2*pi)No. It is circumference/(2*pi)
What is the radius of a circle whose circumference is 28?
pi = 3.1416 ( a constant) Circumference = 2 * pi * radius, so radius = circumference / (2 * pi) So radius = 28 / ( 2 * 3.1416 ) = 4.456 units
How do you find out the circumference of a circle?
Circumference = 2*pi*radius or diameter*pi
Calculate circumference with a radius of 2.250m?
Circumference of a circle = 2*pi*radius or pi*diameter. 2*pi*2.250 = 14.13716694 metres.
