Question

What is the approximate circumference of the circle shown below?

Answer 1

Answer:

$\boxed{\sf 43.35 \ cm}$

Step-by-step explanation:

Apply formula for the circumference of a circle.

$\sf C=\pi d$

The diameter $\sf d$ is 13.8 cm.

$\sf C=\pi (13.8)$

$\sf C= 43.3539786195...$

$\sf{C} \approx \sf{43.35}$

Answer 2

Answer:

43.4 cm

Step-by-step explanation:

Circumference of the circle = 2πr

r = radius, π = $\frac{22}{7}$

f = diameter÷2

 =13.8 ÷ 2

 = 6.9

circumference = $2 * \frac{22}{7} * 6.9$

                        = $\frac{303.6}{7}$

                        = 43.37 cm or 43.4 cm
