Answer 2

Answer:

616 cm²

Step-by-step explanation:

.

Given -

Diameter of circle (d) = 28 cm

.

To find -

The area of circle

.

Solution -

radius (r) = d/2 = 28/2 = 14 cm

.

Area of circle :-

$= \pi {r}^{2} (\pi = \frac{22}{7} ) \\ = \frac{22}{7} \times 14 \times 14 {cm}^{2} \\ = 22 \times 2 \times 14 {cm}^{2} \\ = 44 \times 14 {cm}^{2} \\ = 616 {cm}^{2}$

Hence the area of circle = 616 cm²

.
