Find the circumference of a circle whose diameter is 49cm

Answer 1

The circumference (C) of a circle can be found using the formula C = πd, where d is the diameter of the circle and π is a mathematical constant approximately equal to 3.14159.

Given that the diameter (d) of the circle is 49 cm, the circumference (C) can be calculated as follows:

C = π * d
= 3.14159 * 49 cm
≈ 153.938 cm

Therefore, the circumference of the circle is approximately 153.938 cm.
