Answer:
Perimeter of the circle = 31.42 in(exact value) ≈ 31.40 in (approximate value)
Area of the circle = 78.55 in²
Step-by-step explanation:
Given:
Radius = 5 in
To Find:
Area & Perimeter of the circle
Solution:
Perimeter of the circle:
We know that,
Taking π as 3.142 and substituting values,we obtain
- Perimeter = 2*5*π
- Perimeter = 10π
- Perimeter = 10*3.142
- Perimeter = 31.42 ≈ 31.40 in
Area of the circle:
We know that,
- Area = πr²
- Area = π(5²)
- Area = 25π
- Area =25*3.142
- Area = 78.55 in²
