WebFind the radius, diameter, and circumference of each circle. Radius = 4 inches (Remember the radius goes halfway across the circle.) The diameter is always twice as long as the radius. So, the diameter will be: 4 x 2 = 8 The diameter is 8 inches. For the circumference, we need to choose a formula. WebQuestion 1: Find the area and the circumference of a circle where the radius is 7 cm. Solution: Given: Radius, r = 7 cm Now substitute the radius value in the formulas. Area of Circle, A = πr 2 Square units A = (22/7)× 7× 7 A = 22 × 7 A = 154 cm 2 Circumference of Circle = 2πr units C = 2× (22/7) × 7 C = 2 × 22 C = 44 cm
WebBut, if Radius < 1cm, Then the value of r*r is also a decimal. If, Diameter is 0.5cm The r=2.5cm Therefore, the Area is (pi)r^2 A = (pi)0.25*0.25 = 0.0625(pi) There is no rule that if Radius or Diameter is a decimal, then the Area and the Circumference is also decimal but it ALMOST always shows up that way. Even if it is a decimal no difference.
