Question

Find the area of circle whose radius is 4cm​

Answer 1

Answer:

Area of circle = π*radius*radius

                       = π*4*4

                       = 16π or 352/7

Answer 2

Answer:

50.24sq cm

Step-by-step explanation:

Given that

Radius of circle is 4cm

To find

Area of circle

Solution

As we know that

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

hence

take

$\pi = 3.14$

now

$area \: of \: circle = 3.14 \times 4\times 4$

hence by multiplication we get

$area \: of \: circle = 50.24{cm}^{2}$
