Answer: A
Step-by-step explanation:
The sector of the circle is bounded by 2 radii, and the measure of the central angle that forms the sector is 120 degrees
<h3>How to determine the central angle?</h3>
The given parameters are:
- Area = 75π cm^2
- Radius, r = 15 cm
The area is calculated using
Area = α/360 * πr^2
So, we have:
α/360 * π * 15^2 = 75π
Evaluate the exponent
α/360 * π * 225 = 75π
Divide both sides by 75π
α/360 * 3 = 1
Multiply
α/120 = 1
Multiply both sides by 120
α = 120
Hence, the measure of the central angle that forms the sector is 120 degrees

<span>D = 180 * (n -2)
D = 180n -360
180n = D +360
n = (D / 180) + 2
So, the answer is "A"
And we can test this with a square, sum of angles = 360
n = (D / 180) +2
n = (360 / 180) +2
number of sides = 4
correct
