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 ~

$\qquad \sf  \dashrightarrow \: c = 3.14 \times 4$

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

Answer 2

Given:

• Radius= 2 meters

To find:

The circumference of the given circle.

Solution:

$c = 2 {\pi}r$

$c = 2 \times 3.14 \times r$

$c = 2 \times 3.14\times 2$

$c = 12.56 \: m$

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