Question

Lalitha wants to buy a round carpet of radius is 63 cm for her hall. Find the area that will be covered by the carpet.​

Answer 1

Step-by-step explanation:

area of circle=

$\pi \: r ^2$

radius= 63cm

area of carpet=

$\frac{22}{7} \times {63}^{2}$

$\frac{22}{7} \times 63 \times 63$

$22 \times 9 \times 63$

198×63

12474 cm^2

Answer 2

The area that will be covered by the carpet is 12474 sq.cm

Given :

Lalitha wants to buy a round carpet of radius is 63 cm for her hall

To find :

The area that will be covered by the carpet

Formula :

Area of a circle of radius r unit

= πr² sq.unit

Where r = Radius of the circle

Solution :

Step 1 of 2 :

Write down radius of the circle

Here it is given that Lalitha wants to buy a round carpet of radius is 63 cm for her hall

Thus radius of the circle = r = 63 cm

Step 2 of 2 :

Find area that will be covered by the carpet

Hence the required area that will be covered by the carpet

$\displaystyle \sf{ = \pi {r}^{2} \: \: \: sq.cm}$

$\displaystyle \sf{ = \frac{22}{7} \times {63}^{2} \: \: \: sq.cm}$

$\displaystyle \sf{ = \frac{22}{7} \times 63 \times 63 \: \: \: sq.cm}$

$\displaystyle \sf{ = 12474 \: \: \: sq.cm}$
