Question

What is the formula for the area of a circle with radius 1m (expressed in m2)?

Answer 1

The formula for the area of a circle with radius 1m (expressed in m^2) is

pi x radius^2 = 22/7 x 1^2 = 22/7 = 3.142 m^2. (Ans)

Hope this helps.

Answer 2

ANSWER

Find out the area of a circle with radius 1m.

To proof

Formula of the area of circle

$Area\ of\ the\ circle = \pi r^{2}$

where r is the radius of the circle

As given

radius = 1m

$\pi = 3.14$

put this in the above equation

we get

= 3.14× 1 ×1

= 3.14 m²

Hence proved
