Find the area of the shaded regions:

Area = 18 cm^2

Step-by-step explanation:

1. We can do 360°/80°=4.5

2. To find area of total circle we can do π*(radius)^2= π*(9)^2=81 π

3. Since the shaded region is 4.5 of the whole circle we can do 81/4.5 to find the area of the shaded region.

4. Area = 18 cm^2

56.5486677646 cm²

Step-by-step explanation:

area of whole circle =πr²

area=254.469004941

areaof shaded portion will be 254.469004941÷360×80=56.5486677646

which is approx 56.55 cm².

hope this helps

hi,

6x times 4 is 24x and 5 times 4 is 20, so the answer is 24x+20.

hope this and for a little humor i am groot.

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5
