Question

The formula for the circumference of a circle is 4072-01-01-03-00_files/i0150000.jpg. Determine the circumference when the radius r is 10 cm.

Answer 1

the answer to this is
C ≈ 62.83 cm

Answer 2

Circumference of circle when radius is 10 cm is 62.8 cm.

Explanation:

Given:

Formula for Circumference of the circle = 2πr

where, r is the radius of the circle.

To find: Circumference of circle when radius of circle is 10 cm.

Radius of circle ,r = 10 cm

We use value of π = 3.14

So, Circumference of circle = 2 × 3.14 × 10

= 6.28 × 10

= 62.8 cm

Therefore, Circumference of circle when radius is 10 cm is 62.8 cm.
