Question

Find the area of a circle whose radius is 10 cm (take 22/7)

Answer 1

Answer:

area of circle=πr^2

area of circle=22/7×10×10

area of circle=2200/7

area of circle=314.2

Answer 2

Answer:

314 sq cm

Step-by-step explanation:

Given that

Radius of circle is 10cm

To find

Area of circle

Solution

As we know that

$area \: of \: circle = \pi \times {radius}^{2}$

hence

take

$\pi = 22/7$

now

$area \: of \: circle = 22/7 \times 10 \times 10$

hence by multiplication we get

$area \: of \: circle = 314 {cm}^{2}$
