The radius of a circle, half of its diameter, can help you find the circumference in a couple of steps. First, double the radius to get the diameter (radius x 2, or radius + radius). One you have the diameter, you can use the equation C = πd. If you want to know the circumfe...
Example 1: If the radius of a circle is 30 cm, find its circumference. Solution: r = 30 cm Use the formula to find the circumference of a circle: C = 2\(\pi r\) [Write the formula] = 2 x 3.14 x 30 [Substitute the value of r and \(\pi\)] = 6.28 x 30 = 188.4 Therefor...
Learn the formula used to calculate the area and circumference of a circle. Understand how to apply these formulas to solve math problems with the help of some real-life examples.
The circumference a circle can also be represented in terms of the radius of the circle.We can define the radius of a circle in terms of the diameter through the relationship: d=2∗r Substituting this into the previous equation to find circumference of the circle, we get: ...
∙13yago Best Answer Divide the area by pi then square root your answer which will give the radius of the circle and use 2*pi*radius to find the circumference. Wiki User ∙13yago This answer is: Add your answer: Earn +20pts
Once you have the radius, you can use it to find the circumference or area of the circle. Can I use any two points on the circle to find the radius? Yes, as long as the two points are not on the same diameter of the circle. If the two points are on the s...
