Answer 2

Answer: A) 16.86 square inches

Explanation:

Area of Shaded Area will be the Area of the Rectangle (Total Area) minus the Area of the Circle.

Finding Area of Circle :-

Radius (r) = 1 in
Area = πr^2

Therefore,
= πr^2
= π * r * r
= 3.14 * 1 * 1
=> 3.14

Area = 3.14 in^2

Finding Area of Rectangle (Total Area) :-

Length (l) = 5 in
Breadth (b) = 4 in
Area = l * b

Therefore,
= l * b
= 5 * 4
=> 20

Area = 20 in^2

Finding Area of Shaded Region :-

Area of Rectangle - Area of Circle

Therefore,
= 20 - 3.14
= 16.86

Area = 16.86 in^2
