Given: Use π as 3.14 Radius of circle: 5 inches Width of rectangle: 20 inches Length of rectangle: 10 inches To find: Area of shaded region Solution: Area of 2 circles = 2(πr²) 2(3.14×5²) 2(3.14×25) 2(78.5) 157 inches² Area of rectangle = Length × Width 20 × 10 200 inches² Area of shaded region = Area of rectangle - Area of 2 circles 200 - 157 43 inches²
Area of 2 circles = 2•π•5^2 = 157in^2
Area of rectangle = 20x10 = 200in^2
Area of shaded region = 200-157 = 43
Answer is C
Correeeeeeect!
It literally was asked in my 10th class maths preboard
👍👍👍
Given:
Use π as 3.14
Radius of circle: 5 inches
Width of rectangle: 20 inches
Length of rectangle: 10 inches
To find: Area of shaded region
Solution:
Area of 2 circles =
2(πr²)
2(3.14×5²)
2(3.14×25)
2(78.5)
157 inches²
Area of rectangle =
Length × Width
20 × 10
200 inches²
Area of shaded region =
Area of rectangle - Area of 2 circles
200 - 157
43 inches²
43
You got it 👍
43
