Question

If the diameter of a circle is 14m. Calculate its area

Answer 1

Answer:

Step-by-step explanation

Diameter of the circle=14

Radius of the circle=diameter/2=14/2=7

Area of the circle=πr^2

=22/7×7×7=154m^2

Answer 2

Answer:

Area of circle is

$153.938 {m}^{2}$

Step-by-step explanation:

Given that

Diameter of circle is 14m.

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

$radius = \frac{14}{2}$

hence

$radius = 7m$

hence

$area \: of \: circle = \pi \times {7}^{2}$

put

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

$area \: of \: circle = \frac{22}{7} \times 49$

hence by multiplication and division we get

$area \: of \: circle = 153.938 {m}^{2}$
