Question

Find the area of a circle whose dimater is 18.2cm

Answer 1

Given:-

• Diameter of the circle is 18.2cm.

To Find:-

• Find the area of the circle.

Concept used:-

• Concept used here is Area of the circle.

• As the values are given in the question,just substitute it in the equation and solve it.

Formulae Applied:-

• Area of a circle = πr^2

Solution:-

Given that,

Diameter of the circle is 18.2cm.

Radius = Diameter/2

= 18.2/2

= 9.1

= 9.1cm

Radius of the circle is 9.1cm.

Area = ??

According to the question we have,

Area of a circle = πr^2

= πr^2

= 22/7 × 9.1 × 9.1

= 22 × 1.3 × 9.1

= 260.26

= 260.26cm^2

Hence,

The area of the circle is 260.26cm^2.

Answer 2

$\huge\tt\underline{Answer!!}$

$\fbox{Area = πr²}$

$\longrightarrow$ $\mathtt{Radius \: = \: 9.1 cm}$

$\longrightarrow$ $\mathtt{Area = 22/7 \: × \: 9.1 \: × \: 9.1}$

$\longrightarrow$ $\mathtt{Area \: = \: 260.26 \: cm²}$
