Question

The diameter of a circle is 2 meters. What is the area?
Exact answer in simplest form

Answer 1

22/7

Explanation:

Diameter is 2m

we know,

radius= Diameter/2

r = d/2

r = 2/2

r = 1

Now,

area of circle= πr^2

22/7 * 1^2

22/7 ....... answer

Answer 2

r=d/2

r=2/2

r=1

area=22/7×r

22/7×1

=31/7
