Question

The circumference of a circle is 6.28.What is the area of the circle?

Answer 1

$Circumference=2 \pi r\, r-radius\\ 6,28=2 \pi r|:2 \pi \\ r= \frac{6,28}{2 \pi }= 1\\\\ Area= \pi r^2\\ Area= \pi *1^2= \pi =3,14 unit^2$

Answer 2

Answer:

3.14

Step-by-step explanation:

6.28/3.14=2

Diameter=2

2/2=1

1*1=1

1*3.14=3.14
