Question

"Problem 3
Determine the area of the shaded region.
"

Answer 1

75.36 units²

or

24π

Explanation:

first we find the area of ​​the full circle and then we subtract the area of ​​the small circle

Area of Circle Formulas · Area = π × r²

the expression to solve is:

(π × 7²) - (π × 5²) =

(π × 49) - (π × 25) =

(3.14 × 49) - (3.14 × 25) =

153.86 - 78.5 =

75.36 units²

or

24π (75.36 : 3.14)
