Question

Find the circumference of a circle of diameter 20 m​

Answer 1

Answer:

20π m or 62.83 m

Explanation:

The formula for Circumference is C = 2πr

All you need to find for the formula is the radius, which is half of the diameter.

$r= \frac{1}{2}d$

$r=(\frac{1}{2})(20)$

$r=10$

Then plug the radius into the formula and solve for Circumference

$C= 2\pi r$

$C=2\pi (10)$

$C=20\pi$ or $C= 62.83 m$
