Asector of a circle has a central angle of 45 . find the area of the sector if the radius of the circle is 15 cm.

A = 28.125 * pi cm^2

A = 88.357  cm^2

Step-by-step explanation:

Area of a sector is 1/2 r^2 theta  where theta is in radians

convert 45 degrees to radians

theta = 45 * pi/180 = pi/4

A = 1/2 * 15^2 * pi/4

A =1/2 * 225 * pi/4

A = 28.125 * pi cm^2

A = 88.357  cm^2

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen
