Question

Look at the image and answer it

Answer 1

Answer:

14$\pi$

units = cm

Step-by-step explanation:

circumference = 2 x $\pi$ x r

c = 2 x $\pi$ x 7   - it's 7 because the diameter is 14 and radius is half the diameter

c = 14 x $\pi$

c = 43.98229715

in terms of pi c = 14 $\pi$

units = cm

Answer 2

Answer:

The circumference of circle is 14π cm.

Step-by-step explanation:

Given that the formula of circumference is C = 2×π×r where r represents radius of circle. In this case, diameter of circle is 14cm so the radius will be 7cm. Then, you have to substitute the value into the formula :

$c = 2 \times \pi \times r$

$let \: r = 7$

$c = 2 \times \pi \times 7$

$c = 14\pi \: \: cm$
