Answer:

A≈ 38.5cm^2

Explanation:

Given:

The approximation of pi is 22/7 or 3.141592

The radius is 7/2 or 3.5

Work:

A=πr(2)=π·3.5(2)≈38.48451

now let's round it to 38.5cm^2

Answer: The answer is 38.5 cm^2

Explanation:

Given:

Radius(r) = 7/2

Pie (π) = 22/7

We know that:

The area of Circle is = πr^2 = π * r * r

So, ans is = (22/7) * 7/2 * 7/2 = 38.5 cm^2
