Answer 1

Hope I help you nd this is an answer

Answer 2

Answer:

The radius of circle is 12 m and circumference of circle is 75.36 m

Step-by-step explanation:

Area of circle = $\pi r^{2}$

We are given the area = 144 pi

So, $144 \pi = \pi r^{2}$

$144 = r^{2}$

$\sqrt{144} = r$

$12 = r$

Thus the radius of circle is 12 cm

Circumference of circle = $2\pi r$

                                       = $2\times 3.14 \times 12$

                                       = $75.36$

Hence the radius of circle is 12 m and circumference of circle is 75.36 m
