Answer:
Step-by-step explanation:
10.26 in²
The area (A) of the sector is
A = area of circle × fraction of circle
= πr² ×
= π × 2.8² × ≈ 10.26 in²
x = 24
Firstly, isolate x by adding 2 to both sides.
9 = 3/8x
Then, multiply 8 to both sides.
72 = 3x
Then, divide both sides by 3.
24 = x
Replace y with 31:
31 = 7x -4
Add 4 to both sides:
35 = 7x
Divide both sides by 7:
x = 5
Input x = 5
