arc length of an enclosed circle is 2πr where r is the radius
the atc length of is proportional to the angle subtended at the centre . i.e for this arc it is 1/4th (90°/360°) of the arc length of an enclosed circle.
it is the same relationship with area of a sector

Answer:
Step-by-step explanation:
13x^2 + 56x + 75 = 4x^2 - 10x - 46
You need to first combine like terms, so subtract 4x^2 from both sides,
9x^2 + 56x + 75 = -10x - 46
then add -10x to both sides
9x^2 +66x + 75 = -46
then add -46 to both sides
9x^2 + 66x + 121 = 0
Then use the quadratic formula,
So
a = 9
b= 66
c = 121
That simplifies to
