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...
Example 1. Find the area of the circle. Use \( \frac{22}{7} \)for \( \pi \). Solution: Estimate \( 3\times 8^2=3\times 64=192 \) The area of the circle, \( A=\pi r^2 \) \( =\frac{22}{7}\times 8^2 \)(Substitute\( \frac{22}{7} \)for \( \pi \)and 8...
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: ...
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 Q:How do you find the circumfrence of a circle when you have the area?
