We can compute the circumference of a Circle if you know its radius using following formulae. Circumference or Circle = 2 X PI X Radius We can compute the circumference of a Circle if you know its diameter using following formulae. Given circumference find radius worksheet - Solution. Problem 1: A circular pond has a circumference of 628 feet. A model boat is moving directly across the pond, along a radius, at a rate of 5 feet per second. How long does it take the boat to get from the edge of the pond to the center ? Solution. Dec 03, 2018 · 3rd Way to Calculate Circumference of Circle: When You Know Area of Circle. Firstly, you need to find out radius of circle with help to given area of circle. Formula of area of circle is A = πr2, where “A” is area of circle and “r” is radius of circle or pi multiply by radius squared.

Circle Shape. r = radius d = diameter C = circumference A = area π = pi = 3.1415926535898 √ = square root. Calculator Use. Use this circle calculator to find the area, circumference, radius or diameter of a circle. Given any one variable A, C, r or d of a circle you can calculate the other three unknowns. Aug 22, 2018 · Find the diameter of the circle whose circumference is 132 cm? Explanation. Let, the radius of the given circle be r cm. As we know that, Circumference of the circle = 2πr cm. Given, Circumference of a cicle = 132cm. Therefore, 2πr = 132 from. Sep 19, 2019 · To calculate the radius of a circle by using the circumference, take the circumference of the circle and divide it by 2 times π. For a circle with a circumference of 15, you would divide 15 by 2 times 3.14 and round the decimal point to your answer of approximately 2.39.

Apr 30, 2018 · The distance around the edge of the circle is called the circumference. The distance from one side of the circle to the other, going through the center of the circle, is the diameter. The constant pi, designated by the Greek letter π, is the ratio of the circumference to the diameter of a circle. Area of circle calculator. Let us consider 3 scenarios to calculate the area of a circle. 1 Area of circle when radius r is given. When radius r is given, the area of circle can be found using the formula, \A = \pi r^2\ Where A is the area, and r is the radius. Area of circle calculator.
