Question

find area of circle having radius is 28 cm​

Answer 1

Answer:

area of circle=22/7×28×28

22×4×28=2464

Answer 2

Answer:

Hence, area of the circle having radius 28 cm will be 2464 sq. cm

Step-by-step explanation:

In context to question asked,

We have to determine the area of the circle.

As per question,

We have,

Radius of circle = 28 cm

As we know that,

Radius of circle is the straight line which are drawn from the centre of circle to the circumference of the circle.

As we know that,

Area of circle $=\Pi r^2$

So, for determining the area of circle, we will put the value of radius of circle in above formula,

Thus we will get,

$Area = \Pi r^2\\=>Area = \frac{22}{7} \times 28 \times 28\\=>22 \times 28 \times 4\\=>2464\:cm^2$
