Answer:
166.5 cm squared
Step-by-step explanation:
Multiply 11x11 =121
Multiply 7x6.5 =45.5 (we get the 7 because 18-11=7)
Then we add 121 and 45.5 and get 166.5
First you need to calculate the circumference of the circle:
Circumference = diameter x PI = 16 x PI = 16 * 3.14 = 50.24
The intercepted arc is 15 degrees.
To find the length multiply the circumference by the central angle divided by 360.
Arc length = 50.25 x (15/360) = 2.1 units.
Using subtraction, you would take 3,000 and subtract 1968 from it to leave you 1,032. With that number, the answer to your question is "C"
