Question

The circumference of a circle is 7π in.
What is the area of the circle? ​
A.3.5pi m^2
B.12.25pi m^2
C.14pi m^2
D.49pi m^2

Answer 1

Answer:

The correct option is B.

Step-by-step explanation:

It is given that the circumference of a circle is 7π units.

The circumference of the circle is

$S=2\pi r$

$7\pi =2\pi r$

$7=2r$

$r=3.5$

The area of the circle is

$A=\pi r^2$

$A=\pi (3.5)^2$

$A=12.25\pi$

The area of circle is 12.25π square unit.

Therefore the correct option is B.
