Find the exact length of the radius and the exact circumference of a circle whose area is:
a) 36π m2 | b) 6.25π ft2 |
a)
To Find:
The length of the radius and the circumference of the circle whose area is 36π m2.
It is given that the area of the circle is 36Ï€ m2.
The area of the circle is
Therefore,
Now it becomes,
b)
To Find:
The length of the radius and the circumference of the circle whose area is 6.25 ft2.
