Question

Find the circumference of..

Answer 1

7π cm

Explanation:

The formula for the circumference (C) of a circle, given its diameter (d), is:

`C = \pi d`

For the given circle, the diameter is 7 cm, so we can find the circumference by substituting d = 7 into the formula:

`C = \pi \cdot 7=7\pi \; \sf cm`

Therefore, the circumference is 7π cm.
