So the formula for the circumference of a circle is π x diameter
Since we know the the circumference already, we just divide that by π:
12π / π = 12
Now we halve the diameter to get the radius:
12 / 2 = 6
The area of a circle is π x radius²
So the area is:
·π x 6² = 36π· (or 113 not in terms of π)
Answer:
25
Step-by-step explanation:
Answer with Step-by-step explanation:
Let A is non-singular
We have to prove that 
is unique.
Suppose B and C are inverse of A such that
and AC=I
By using property 
Hence, the inverse of A is unique.
