Question

What if the perimeter and area for the following figure?

Answer 1

Perimeter of the circle = 31.42 in(exact value) ≈ 31.40 in (approximate value)

Area of the circle = 78.55 in²

Explanation:

Given:

Radius = 5 in

To Find:

Area & Perimeter of the circle

Solution:

Perimeter of the circle:

We know that,

• Perimeter = 2πr

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
