Question

The circumference of a circle is 62.8m . Find the radius of circle (take pie=3.14)

Answer 1

If S is the circumference of the circle and R is the radius we

have that S=2π⋅R⇒2R=Sπ⇒2R=62.83.14⇒2R=20

Hence the diameter is d=2R=20m

there fore R=20/2
radius=10cm

Answer 2

radius is 10.........
