Answer 1

62.83185

Explanation:

C=2πr=2·π·10≈62.83185

Answer 2

`\qquad\qquad\huge\underline{{\sf Answer}}♨`

Circumference of circle is :

`\qquad \tt  \dashrightarrow \:\pi d`

where,

• d = diameter of circle

`\qquad \sf  \dashrightarrow \:c = 20 \pi \: \: cm`

Now, let's plug approximate value of pi

`\qquad \sf  \dashrightarrow \:c = 20 * 3.14\: \:`

`\qquad \sf  \dashrightarrow \:c = 62.8 \: \: cm`
