Explain your answer for /brainlest!

circle o has a diameter of 15 cm. points t and p lie on the circle, and mpt = 180. find the area of sector top. leave your answer in terms of pi.

Well the area of a sector formula is:
A = (degree/360) × πr²
We know the degree so keep that in mind. The diameter is 15  the radius is half of the diameter so the radius is 7.5. Now we plug these into the equation:
A = (180/360) × π7.5²
A= (1/2) × π56.25
A= 28.125 × π
A = 28.125π

Dis the correct answer
