Question

Find the area of the circle whose
circumference is 16π units (in sq.units).​

Answer 1

Answer:

ANSWER

To find the quadrant of a circle we will have to first determine the circumference of the circle which is π units (in sweat.units)

Here, the circumference being 44 cm

16πr=616

2(

7

22

)r=616

r=

22×2

616×7

=

44

4312

=98 cm

Therefore, radius of circle, r=98 cm

Now, Area of circle=πr

Answer 2

Answer:

64 π square units

circumference=2πr

r=cirumference/2π

r=16π/2π

r=8

area of circle=πr²

= π8²

=π64
