Given the radius, r, the area is pi*r^2.
If given the diameter d, the radius is d/r so the area is 0.25*pi*d^2
If given the circumference, c, the radius is c/(2*pi), so area = 0.25*(c^2)/pi

What is the formula for the diameter or a circle?
If you are given the radius of the circle, you can use the formula: diameter = 2*radius If you are given the circumference of the circle, you can use the formula: diameter = circumference/pi
How do you calculate the circumference of a circle given the diameter or the radius?
Circumference = diameter*pi
How do you find length and width given the circumference?
If you mean the diameter and radius of a circle given the circumference it is:- diameter = circumference/pi radius = circumference/(2*pi)
What is the circumference of a 3 inch circle?
circumference= pi(3.14) by the diameter. if your given the radius, double the radius and times by pi.
How do you find circumference of a circle given?
circumference of a circle = 2*pi*radius or pi*diameter
How do you find distance if radius is given?
Diameter of a circle = 2*radius Circumference of a circle = 2*radius*pi
Given the circumference of a circle what is the radius?
Circumference equals the diameter times pi. The diameter is 2 times radius. Radius equals Circumference divided by pi then divided by 2.
What is the formula for the circumference of a circle given a radius?
Circumfrence=diameter X 3.14 (diameter=2 X radius)
What is the circumference of a circle with the diameter of 16in?
Circumference of a circle is the diameter times pi or 2pi times the radius. Given the diameter, circumference = 16 times pi. So, the circumference is 16pi or 50.265
How do you find the circumference of a circle given the radius?
Easy. First, double the radius to get the diameter. Next, multiply the diameter by Pi (about 3.1416) to determine the circumference.
What is the formula to find circumference when you are given the radius?
To find the circumference of a circle the formula is: 2*pi*radius or diameter*pi
How do you find the area of a circle without knowing the radius?
If the circumference or diameter is given then you can find the radius or simply measure the distance from the centre of the circle to the circumference.
