Find the area of the shaded regions.

The largest circle has radius OP = 8 cm, the next largest circle has radius AO = 4 cm, and the smallest circle has diameter AB = 4 cm so its radius has length 2 cm.

These circles have respective areas of 64π cm², 16π cm², and 4π cm².

The area of the shaded region is then

64π cm² - 16π cm² + 4π cm² = 52π cm²

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
