What is the area of a sector that has a radius of 25 mm and has an angle measure of 50°?
A 3,120 72 π mm2
B 100π mm2
C 15 46 π mm2
D 3,125 36 π mm2

The area of the sector is 86.81π mm²

Explanation:

Given:

Radius of the sector, 25mm

Angle, α = 50°

Area of the sector, A = ?

We know:

Area of the sector =

On substituting the value, we get:

Therefore, the area of the sector is 86.81π mm²

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
