Centralangle/360 times area of circle=sector area
120/360 times pi8²=
(1/3)(64pi)=64pi/3 square inches
X = measure of each of the legs
"perimeter is 8 more than 2 times one of the legs" ---> P = 2x+8
P = 28 is the given perimeter
So,
P = 2x+8
28 = 2x+8
2x+8 = 28
2x = 20
x = 10
If x = 10, then the two legs add up to x+x = 10+10 = 20
Leaving P-20 = 28-20 = 8 inches left over for the base
You have the correct answer (choice D, 8 inches) though your steps are a bit confusing at some parts. Such as the part where you wrote 2x = 10 twice. I think I know what you were trying to say.
Answer:
Your exact value should be 10h
Step-by-step explanation:
I put it into the calculator and that's what came out.
Answer:
Y is NOT a function of X
Step-by-step explanation:
I guess this because it doesn't go in a pattern.
Answer:
7a+1 +9 × 7a÷7a+2- 45 ×7a
7a+1 +9 × 1+2-45 ×7a
7a+1 +9 + 2-315a
7a+12-315a
12-308a
4(3-77a)
