circle O has a circumference of 36tt cm. what is length of the radius r
Accepted Solution
A:
Answer: 5.73cmStep-by-step explanation:Given parameters: Circumference of the circle = 36cmUnknownLength of the radius = ? Lets represent the radius by rSolutionThe circumference of a circle is the defined as the perimeter of a circle. The formula is given as: Circumference of a circle = 2πr Since the unknown is r, we make it the subject of the formula: r = [tex]\frac{circumference of the circle}{2π}[/tex] r = [tex]\frac{36}{2 x 3.142}[/tex] = [tex]\frac{36}{6.284}[/tex] = 5.73cm
