Answer:
25.12 cm^2
Step-by-step explanation:
Step 1: Determine what fraction of a whole circle is created by a 45 degree angle: It is 1/8.
Step 2: Determine the area of the entire circle: It is A = pi(8 cm)^2, or
A = 3.14(64) cm^2 = 200.96 cm^2
Step 3: Multiply this area by 1/8: (1/8)(200.96 cm^2) = 25.12 cm^2
