Question

Answer

Given, area of circle = 616 cm²

We know that, the area of a circle is given by the formula:

Area = πr²

Where, r is the radius of the circle and π (pi) is a constant value approximately equal to 3.14.

So, we can find the radius of the circle as:

r = √(Area/π) = √(616/π) ≈ 14 cm

Now, we can find the perimeter of the circle using the formula:

Perimeter = 2πr

Substituting the value of r, we get:

Perimeter = 2π(14) ≈ 88 cm

Therefore, the correct answer is option B) 88 cm.
