Solution Given parameters are Radius of a circle, r = 15 cm Diameter of a circle is given by 2r = 2 × 15 = 30 cm Area of a circle is given by π r 2 = π ×15 2 = π × 225 = 706.95 cm 2 WebAnswer: Radius = 4 in., diameter = 8 in., circumference =25.12 in. Diameter = 6 feet (as shown in the above picture) The diameter is always twice as long as the radius. So, if our diameter is 6 feet, the radius must be half as long as that. 6 ÷ 2 = 3 So the radius is 3 feet long. For the circumference, we need to choose a formula. hot rummy rules
