Question

diameter of a circle is 36m find its area​

Answer 1

Step-by-step explanation:

area of circle= πr^2

(22/7)×(d/2)^2

=(22/7)×(36/2)^2

=(22/7)×18^2

=22/7×18×18 m^2

Answer 2

Answer:

Area of circle is

$1017.87 {m}^{2}$

Step-by-step explanation:

Given that

Diameter of circle is 36m.

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

$radius = \frac{36}{2}$

hence

$radius = 18m$

hence

$area \: of \: circle = \pi \times {18}^{2}$

put

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

$area \: of \: circle = \frac{22}{7} \times 18*18$

hence by multiplication and division we get

$area \: of \: circle = 1017.87 {m}^{2}$
