A sector with an area of 26pi cm^2 has a radius of 6cm. What is the central angle measure of the sector in radians?
A: 13pi/9
B: 9pi/13
C: 13pi/18
D: 18pi/13

A

Step-by-step explanation:

The area (A ) of the sector is calculated as

A = area of circle × fraction of circle

   = πr² × ( x is the measure of the central angle ) , thus

π × 6² × = 26π

36π × = 26π (cancel 36π and 2π )

18x = 26π ( divide both sides by 18 )

x = = → A

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
