Question

Does someone mind helping me with this problem please? Thank you!

Answer 1

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

Let's calculate the circumference ~

`\qquad \sf  \dashrightarrow \: c = \pi d`

where,

• d = diameter = 2 × r = 2 × 2 = 4 cm

now, plug in the values ~

`\qquad \sf  \dashrightarrow \: c = 3.14 * 4`

`\qquad \sf  \dashrightarrow \: c = 12.56 \: \: m`

Answer 2

Given:

• Radius= 2 meters

To find:

The circumference of the given circle.

Solution:

`c = 2 {\pi}r`

`c = 2 * 3.14 * r`

`c = 2 * 3.14* 2`

`c = 12.56 \: m`

Hence, the circumference of the given circle is 12.56 meters.
