What is the radius of a circle whose circumference is 22m,formula;C=2 pi r
C = 2*pi*r
22 = 2 * 3.14 * r
22 = 6.28r
22/6.28 = r
3.503 = r
To find the radius of a circle, you can use the formula C = 2πr, where C is the circumference of the circle and r is the radius.
In this case, the given information is that the circumference is 22 meters (m). By substituting this value into the formula, you have:
22 = 2πr
To solve for the radius, you can isolate the variable r. First, divide both sides of the equation by 2π:
22 / (2π) = r
This gives you the value of r, which is the radius of the circle. To calculate the numerical value, use a calculator to evaluate the fraction 22 / (2π). The result will give you the radius of the circle in meters.
