Answer 1

Question:

If the radius of circle is 4 cm then find its circumference?

Answer:

Circumference of circle =25.12.

Answer 2

Answer:

Solution :-

The formula for the circumference of a circle = C = 2πr or C= πd

=> where r represents length of r and d represent length of diameter.

=>The length of a diameter is 2r

=> C= πd. Using this formula,

=> we know that r= 4cm.

=> Thus, C= 2(4)π = 8π ≈ 25.13 centimeters. answer
