Question

The circumference of the circle is 88cm. Find it's area.

Answer 1

Given, 2πr = 88 cm

$\bf\huge r=\frac{88\times7}{2\times22} = 14 cm$

Area = πr^2

Area = $\bf\huge\frac{22}{7} \times14\times14$

Area = 616 cm^2

Answer 2

The circle’s area is 616.47 sq.cm

Given:

Circumference = 88 cm

Step-by-step explanation:

A circle is a closed surface such that the center of it is equidistant from all the points on the circle.

Circumference of a circle is the perimeter or length of the whole edge.

Circumference of a circle = 2Πr

Where,

r is the radius of the circle.

$2 \pi r=88$

$r=\frac{88}{2 \pi}=\frac{44}{\pi}=\frac{44}{3.14}$

$\therefore r=14.012 cm$

Area of the circle is the total value inside the circle’s circumference.

The formula for area of a circle = $\pi r^2$

Where,

r is the radius of the circle which is the length included from center towards any point on the circle.

$\text{Area}=\pi \times 14.012 \times 14.012=3.14 \times 196.33$

$\Rightarrow \text { Area }=616.47 \ \mathrm{cm}^{2}$
