Answer:
57 square inches
Step-by-step explanation:
First consider that a 45 degree sector of a circle is 45/360 of the area of the full circle from which it is cut. This comes out to 1/8 of the full circle area.
The area of a circle of radius 12" is A = π(12 ")^2, or A = 144π.
The area of the sector in question is 1/8 of that, or
A = (1/8)(144π), or A = 18π square inches, or approximately 57 square inches.
