Here's the equation for the area of a semicircle: A = (πr²)/2
Based on this, let's solve for this area in terms of π (pi):
A = π(10²)/2 = 100π/2 = 50π
The area of the semicircle, I believe, is 50π. Hope this helps, let me know if I messed up!
There are 10 sides becuase the equation set up is and equal it to 144.
Solve for n and get 10

Answer:
A) 9x^2-12x+4
Step-by-step explanation:
to find out whether an equation is a perfect square when we take the square root of "a" and the square root of "c" and double their sum. The result should be the middle term, -12
so
square root of 9; 3
square root of 4: 2
2((3*-2))=-12
now we can take the square root of 9x^2(which is 3x) and the square root of 4(-2) and put it in a expression like this
(3x-2)^2
hope this helps!
