WebThe perimeter of a semicircle formula is defined as the sum of half of the circumference of the circle and the diameter of a circle. It is expressed as, The circumference of a circle is C = πd or C = 2πR. The perimeter of a semicircle formula = (πR + 2R) units, or R(π + 2). where, R = radius of a semicircle; π(pi) is 22/7 or 3.142 ... WebThe circumference of a circle is pi times its diameter. Circumference = π * Diameter Diameter of a Circle The diameter of a circle is the distance from one edge to the other, passing through the center. It is twice the radius.

WebThe circumference of a circle is 440 yards. Find the diameter and radius of the circle. Solution. Circumference = 2 * π* R = 2πR. 440 =2 * 3.14 * R. 440 = 6.28R. Divide both sides by 6.28 to get, R = 70.06. Therefore, the radius of the circle is 70.06 yards. But, since the diameter is twice the radius of a circle, the diameter is equal to 140 ...
