Find the area of the shaded regions. Give your answer as a completely simplified exact value in terms of π (no approximations).
Anna [14]
The shaded areas add to 2/5 of the area of the circle, which is given by
  A = πr²

Then the shaded area is ...
  (2/5)A = (2/5)π(10 in)²
  shaded area = 40π in²

A quadrilateral has the following vertices on a coordinate plane:
dolphi86 [110]
<h3>Answer:  4</h3>

================================================

Explanation:

We'll only focus on points J and K.

J = (3, -6)

K = (-1, -6)

Because these two points have the same y coordinate (which is -6), this means we can ignore those values and subtract the x coordinates

3 minus (-1) = 3 - (-1) = 3 + 1 = 4

Or we could plot points J and K on the same xy grid system, and count out the number of spaces between J and K. You should count out 4 spaces.

This means segment JK is 4 units long.
