WebGiven, Radius of the circle = 28 cm. To find the circumference of the circle, we will use the circumference formula: 2πr = 2 × 22/7 × 28 = 176 cm. Therefore, the circumference of the circle is 176 cms. Example 2: The … WebThe formulas for the circumference of a circle are given as follows: When the radius is given: Circumference of a circle formula = 2πr; When the diameter is given: Circumference of a circle formula = π × D; Where, r = radius of the circle. D = diameter of the circle. π = Pi with the value approximated to 3.14159 or 22/7. Radius of a Circle
WebOct 7, 2016 · Hence, we should look for a quantity whose units are metres / revolution. Using conversion factors, we obtain: ( 50 km 1 hr) ( 1000 m 1 km) ( 1 hr 60 min) ( 1 min 500 revolutions) = 5 m 3 revolutions = 1. 6 ¯ metres 1 revolution.
