Answer 2

Given -

Circumference of circle is 50 cm

To find -

The area of circle

Solution -

As we know that,

Circumference of circle = $2 \times \pi \times r$

Put the given values in these formula we get

$50 = 2\pi \times r$

$\frac{50}{2\pi} = r$

$\frac{25}{\pi} = r$

The value of π is 3.14 .

$\frac{25}{3.14} = r$

$r = 7.96$

So,

Radius (r) is 7.96 cm.

Area of circle = $\pi {r}^{2}$

Put the value of r we get

Area of circle = $\pi \times {7.96}^{2}$

Square means multiply the given values with itself twice.

Square of 7.96 is 63.36

Area of circle = $\pi \times 63.36$

The value of π is 3.14.

Area of circle = $3.14 \times 63.36$

Area of circle = $198.95$

Hence,

Area of circle is 198.95 ${cm}^{2}$
