Question

Please help!!

Answer 1

The answer is 120 $\pi$

Answer 2

For this case we have that the remaining angle is given by:

$theta = 360 - 60 = 300$

Then, the area of the region that is not shaded is given by:

$A = (\frac{300}{360}) * (\pi) * (r ^ 2)$

Where,

r: radius of the circle.

Substituting values we have:

$A = (\frac{300}{360}) * (\pi) * (12 ^ 2)\\A = 120\pi$

Answer:

the area of the sector that is not shaded is:

$A = 120\pi$
