Question

Find the area of circle having:(take 22/7 when radius is 10 cm

Answer 1

Answer:

area of circle= πr²

= 22/7 × 10× 10

= 314.29m²

Answer 2

Answer:

Hence, area of the circle having radius 10 cm will be approximately 314.3 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 = 10 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,

$Area = \Pi r^2\\=>Area = \frac{22}{7} \times 10 \times 10\\=>\frac{22 \times 100}{7}\\=>\frac{2200}{7} =314.2857 \approx 314.3\:cm^2$
