Answer:
25π - 24 cm²
Step-by-step explanation:
area of circle:
A = πr²
A = π(5²)
A = 25π
Area of triangle:
base = 6
height = 5 - 1 = 4
(1/2)(6 * 4) = 12
there are 2 triangles so unshaded area is 24 cm²
Area of shaded region = 25π - 24 cm²
I think it's Acute i hope it's right.
The way to find an unknown is to isolate it.
n+14(-14)=15(-14)
n=1
Then we can check our answer by plugging it into the equation.
1+14=15
15=15
So n=1.
