Question

The diameter of a circle is 10m.Find its area.

Answer 1

diameter=10m
radius=10/2=5m
area=22/7*5*5=78.57m^2
is it okkkk?

Answer 2

Answer:

Area of circle is

$78.539 {m}^{2}$

Step-by-step explanation:

Given that

Diameter of circle is 10m.

To calculate

Area of circle

Solution

As we know that

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

As here diameter is given and we know that radius is always half of its diameter hence

$radius = \frac{10}{2}$

hence

$radius = 5m$

hence

$area \: of \: circle = \pi \times {5}^{2}$

put

$\pi = \frac{22}{7}$

$area \: of \: circle = \frac{22}{7} \times 25$

hence by multiplication and division we get

$area \: of \: circle = 78.539 {m}^{2}$
