Answer 2

Given:-

The diameter of a circle is 7 cm

To Find:-

Area of Circle.

Solution:-

Diameter = 7 cm ( Given )

$\therefore$ Radius = $\frac{7}{2}$ = 3.5 cm

Now,

We know,

Area of Circle = πr²

So,

Area of Circle = $\frac{22}{7}$ × $\frac{7}{2}$ × $\frac{7}{2}$

Area of Circle = $\frac{1078}{28}$ [ Divide 1078 by 28 and you will get 38.5 ]

Area of Circle = 38.5

$\bf Area \: of \: Circle \: is \: 38.5 \: sq. \: cm \: [Ans]$
