Question

The circumference of a circle is 62.8 cm . Find the radius of the circle . Take pi=3.14 .

Answer 1

Answer:

10 cm

Step-by-step explanation:

Circumference of circle is 2pi* r

Thus , 2 * pi * r = 62.8 cm

2 * 3.14 * r = 62.8 cm

6.28 * r = 62.8 cm

r = 62.8 cm /6.28 = 10 cm

Thus radius is 10 cm

Answer 2

Diameter of the circle is 20 cm

Let the diameter be d

As we know that

Circumference of the circle with diameter d is πd

Given circumference is 62.8 cm

⟹πd=62.8

⟹d= 62.8/3.14=20 cm

So diameter of the circle is 20 cm
