WebNov 28, 2024 · Find the diameter of a circle with a circumference of 21.98 feet. To work on this problem, you will need the formula for finding the circumference of a circle using the diameter. \(C=\pi d\) First, fill in the given information. \(21.98=(3.14)d\) Next, solve the problem by dividing both sides by 3.14. WebJan 9, 2013 · 1. Since the radius is 6 then r = 6 and the circumference is C = 2*pi*6 or 12*pi. 2. The circumference is 24pi so that must equal the equation for circumference or 24pi = 2*pi*r; You can divide both sides of the equation by 2pi so then r = 12. 3. Solve the same way as question 2, divide by 2pi to get r = 16 then plug into the equation for area.
WebSep 26, 2024 · If you don’t know the radius, however, you can still calculate the area if you are given the length of the circle’s circumference or perimeter. You can use a two-step process, solving first for the radius using the formula for the circumference: circumference = 2 π ( r ) {\displaystyle {\text{circumference}}=2\pi (r)} . WebMar 27, 2024 · Alternatively, you can solve the equation A = πR 2 in reverse to find R, then plug R into the circumference equation. Both equations provide the same result. Steps. ...
