B is the correct answer. The absolute value of something will always be positive. ALWAYS.
N would equal 45° since the tiny square means its 90°. 90-45=45.
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
68 ( p+11 bc when u add 12 +48 u get 68 and then u times it by 22 it's that what's u get
