How do you find the radius of a circle only knowing the circumference?
The equation for finding the circumference of a circle is diameter times pi so reverse it to circumference divided by pi which leaves the diameter. The diameter is twice as big as the radius so divide the diameter by 2 and you will find the radius.
What is the formula for finding perimeter of a circle?
The formula for the circumference of a circle is pi * diameter or (2 radius.)
If 2.5 is the diameter then what is the radius?
Radius is 1/2 of a diameter. 2.5/2 is 1.25. Radius is necessary in finding the circumference and area of a circle.
What is the formula for finding circumfernce?
circumference of a circle = 2*pi*radius or pi*diameter
If you Give a circle with a diameter of 4 what is the circumference?
the equation for the circumference of a circle is 2*radius*pi, or since the radius is half of the diameter 2*radius=diameter, we can simplify the equation to the circumference of a circle=diameter*pi
How do you find a diameter of a circle?
If you have the circumference: circumference = (pi) * diameter diameter = circumference / (pi) If you have the area: area = (pi) * radius * radius radius = square_root(area / pi) radius = diameter / 2 diameter = 2 * square_root(area / pi)

circumference of a circle = 2*pi*radius or pi*diameter
If you Give a circle with a diameter of 4 what is the circumference?
the equation for the circumference of a circle is 2*radius*pi, or since the radius is half of the diameter 2*radius=diameter, we can simplify the equation to the circumference of a circle=diameter*pi
How is finding the area of a circle similar to finding the circumference of a circle?
They both use pi:- circumference = 2*pi*radius or diameter*pi area = pi*radius2
What is the diameter and radius of a circle if the circumference is 37.68?
The diameter and radius of a circle if the circumference is 37.68 are:Diameter = 11.99Radius = 5.997
What is the radius of a circumference circle?
radius is half the diameter of a circle.
What is the circumference of the circle with a 6 inches radius?
The circumference of a circle equals the diameter times pi. The diameter is two times the radius. So a circle with a radius of 6 would have a diameter of 12, and a circumference of 12pi.
The circumference of a circle exceeds its radius by 37cm.what is the diameter of the circle?
The diameter of any circle is twice its radius.
What is the circumference of a circle with radius 5x?
Circumference of a circle = 2*pi*radius or diameter*pi
