Answer 2

Answer:

Area of circle is 314.159 cm sq

Step-by-step explanation:

Given that

Diameter of circle is 20cm

To find

Area of circle

Solution

As we know that radius of circle is always half of its diameter hence

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

$radius = \frac{20}{2}$

by division we get

$radius = 10cm$

now as we know that

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

$area \: of \: circle = \pi \times {10}^{2}$

put

$\pi = 3.14$

$area \: of \: circle = 3.14 \times {10}^{2}$

by multiplication we get

$area \: of \: circle = 314.159 {cm}^{2}$
