Answer:
0.98
Step-by-step explanation:

Answer:
1. y = 7x. This is an example of direct variation as the value of y also increases if the value of x is increased.
2. xy = 24. This is an example of inverse because the value of y is decreased when x is increased.
3. F = 4/R. This is inverse variation for the same reason as number 2.
4. m/n = 4. Direct variation. For the same reason as number 1.
5. i = 2pr. Joint variation. The value of i is dependent on the values of two other variables.
6. R = cl/r². Joint variation.
7. A = pir². Direct variation. I believe pi here is for π, leaving only A being dependent only to value of r.
8. V= pir²h. Joint variation.

Answer: 
Step-by-step explanation:
We know that the circumference of a circle is given by :-
, where r is the radius of the circle .
Given : Circumference of circle = 16 cm
Then, 
i.e
(1)
We know that the area of circle is given by :-

i.e.
[From (1)]
i.e.
i.e.
Put 
Hence, area of circle =
