Answer 1

Answer:

If radius is r cm, then area=πr

2

.

Answer 2

The area of a circle of radius r cm is π$r^{2}$ c$m^{2}$,

• A circle's area is that particular amount of space that it takes up in a two-dimensional plane. The area of a circle, on the other hand, is the particular space occupied within the boundary/circumference of a circle.
• The area of a circle is π$r^{2}$ uni$t^{2} / m^{2} /cm^{2}$. Where π=3.14 or  $\frac{22}{7}$.
