Answer:
40π in²
Step-by-step explanation:
The area (A) of sector ODC is calculated as
A = area of circle × fraction of circle
= πr² ×
= π × 10² × = = 20π cm²
Sector OAB is congruent to sector ODC, thus
area of shaded regions = 2 × 20π = 40π in²
126 in²
10.10.0,628.2=126
4(x + 1) = 8
4x+4=8
4x=8-4
4x=4
x=4/4
x=1
1/8
1/6 × 3/4
Multiply across top, then bottom
1×3=3
6×4=24
Then reduce if necessary.
3/24
Divide top and bottom by 3
3÷3=1
24÷3=8
You should get 1/8
