Circumference of a circle = 2*pi*radius or pi*diameter
This is the equation for the circumference... C= 2 x r x pi r = the length of the radius pi = 3.14159 To find to circumference just find the radius of your cricle that you want to find the circumference of. then simply multiply 2 and 3.14159 by the radius and your circumference is the answer
You already know the radius.
double the radius or multiply by 2 the radius
It depends on the values you have. The base of a cylinder is a circle. If you know the circle's diameter, half it to find the radius. If you know the circle's circumference, divide by 2pi to find the radius. If you know the circle's area, divide by pi and take the square root to find the radius.
Multiply the radius by 2 and multiply the result by 3.141592654....(pi)
7*pi which is about 22 units of measurement

Diameter * pi (3.14159...) = circumfrerence
You already know the radius.
double the radius or multiply by 2 the radius
at the equator.
It depends on the values you have. The base of a cylinder is a circle. If you know the circle's diameter, half it to find the radius. If you know the circle's circumference, divide by 2pi to find the radius. If you know the circle's area, divide by pi and take the square root to find the radius.
Diameter = 2*Radius
Well, if you know the diameter you divide that by two to get the radius.
If the radius is 42 meters, then you already know the radius.
