Answer 1

Answer:

How to find the circumference of a circle

1. Determine the radius of a circle. .

2. Substitute this value to the formula for circumference: C = 2*T* R = 2** 14 = 87.9646 cm.

3. You can also use it to find the area of a circle: A = * R2 = 1 * 142 = 615.752 cm2

Answer 2

Answer:

Circumference of circle=2πr

Area of circle=πr^2

Given, that 2πr=πr^2

So, radius of circle=2
