Answer:
13.76 square meters
Step-by-step explanation:
The side of square is 8 meters.
So, the diameter of circle = 8 meters.
⇒ Radius = (diameter of circle) ÷ 2 = 8 ÷ 2 = 4 meters
Shaded region = Area of square - Area of circle
= (Side × Side) - π × (radius)²
= 8 × 8 - π × 4 × 4 {∵ π = 3.14 or 22÷7}
= 64 - 50.24
= 13.76 square meter
x=120°
sum of all angles in a triangle is equal to 180
let the unknown angle be
Total = 2,400 * (1 + (.083/4))^4*5
Total = 2,400 * (1.02075)^20
Total = 2,400 * 1.5079528829
Total = 3,619.09
