Answer:
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
Step-by-step explanation:
multiply it
x²-3x+3x-9=0
x²-9=0
x²=9
square root both side we get
x=3
