Question

Find the radius of a circle is the circumference is 50.24cm. (Hint: Use C=2 x pi x radius to work backwards. Use the following set up and solve for the radius: 50.24=2 x 3.14 x radius)

Answer 1

r = 8 cm

Explanation:

Circumference of circle = 50.24 cm

2πr = 50.24

2 * 3.14 * r = 50.24

`r = (50.24)/(2*3.14)=(5024)/(2*314)\\\\\\\\`

r = 8 cm
