C. 1.57
D. 9.42

Answer 1

Answer:

The answer is 9.42, Yash :) ~Anusri

Step-by-step explanation:

Basically, you can set up two proportions (one for each concentric circle).

x/25pi=45/360 will get you an area of 9.81 for the smaller circle and x/49pi=45/360 will get you an area of 19.4225 for the larger circle. Subtract those and get 9.42.

Have fun Yash
