Hence the correct answer is C) -23
Further explanation:
We have to put the values of m and n into both expression first separately and then multiply the answers.
Given expressions are:

The values are:

Putting the values in expression 1: 

Putting the values of m and n in second expression

Answer:
116 cm²
Step-by-step explanation:
The area of a circle = πr² ← r is the radius
shaded area = external area - internal area
                       = π × 6.5² - π × 2.3²
                       = π( 42.25 - 5.29)
                       = π × 36.96 ≈ 116 cm²
