Question

The radius of a circle measures 10 cm. What is the circumference of the circle?Use 3.14 for m, and do not round your answer. Be sure to include the correct unit in your answer

Answer 1

Answer:

62.8 cm

Explanation:

The circumference of a circle is given by

$C=2\pi r$

where r is the radius.

Now in our case, r = 10 cm and we use 3.14 for π; therefore,

$C=2\times3.14\times10$

which we evaluate to get

$\boxed{C=62.8\; cm\text{.}}$

Hence, the circumference of the circle is 62.8 cm.
