Answer:
9.43 ft
Step-by-step explanation:
First, we need to find the area of the entire circle(shaded & unshaded), which is 12.57, with a radius of 2 ft. Next, we find the area of the white area, and NOT the shaded area, which is 3.14, with a radius of 1 ft. Now, we need to subtract the white area(3.14) from the total area(12.57), which is 9.43.
Hope this helps!

Step-by-step explanation:
Answer:
764
Step-by-step explanation:
Set Abe as x
set Bella as y
set Carlos as z
<span>Bella has earned 10 less credits than Abe
y=x-10
</span><span>Carlos has earned two less than double the number of Abe’s credits
</span><span>z=2x-2
</span><span>Altogether, they have earned a total of 136 credits
</span><span>x+y+z=136
replace y with x-10
replace z with 2x-2
x+(x-10)+(2x-2)=136
solve for x
4x-12=136
4x=148
x=37
We now know Abe earned 37 credits
To find how much Bella earned plug in 37 for y=x-10
y=27
To find how much Carlos earned plug in 37 for z=2x-2
z=72
Therefore,
Abe earned 37 credits
Bela earned 27 credits
Carlos earned 72 credits

The binomial theorem for a binomial in the format (x + y) to the fourth power is
x⁴ + 4x³y + 6x²y² + 4xy³ + y⁴
So now we plug in for the x- and y-values
a⁴ + 4a³(2b) + 6a²(2b)² + 4a(2b)³ + (2b)⁴
Simplify this to become:
a⁴ + 8a³b + 6a²(4b²) + 4a(8b³) + 16b⁴
Now simplify to:
a⁴ + 8a³b + 24a²b² + 32ab³ + 16b⁴
