Question

Find the area of circle whose :
(i) radius = 10 cm​

Answer 1

Step-by-step explanation:

• Area of circle = πr^2
• Radius = 10cm
• Area of circle = 10*10π cm = 100π cm^2

Answer 2

Answer:

Area of circle is 314.159 sq cm

Step-by-step explanation:

Given that

Radius of circle is 10cm

To find

Area of circle

Solution

As we know that

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

put

$\pi = 3.14$

now

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

by multiplication we get

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