See the attachment for the solution

Answer 2

Step-by-step explanation:

The diameter of the circle is 28cm, so its radius is 14cm.

We know that the area is found by πr^2.

Putting the values

$\pi \times {14}^{2} \\ \\ \pi \times 196 \\ \\ \frac{22}{7} \times 196 \\ \\ 616 \: {cm}^{2}$

Also, the area is found by 2πr.

Putting the values in the equation

$2 \times \pi \times r \\ \\ 2 \times \frac{22}{7} \times 14 \\ \\ 88cm$
