Circumference of a circle = 2πr
So,
F(6) = 7(6) - 4
f(6) = 42 - 4
f(6) = 38

An equal mass of silver will displace a different volume of fluid than that displaced by gold.
<h2>Archimedes principle</h2>
According to the Archimedes principle, when an object is partially or completely immersed in water, the object will experience a force that displaces its own weight of fluid.
Therefore, when the jeweler deceptively replaced “an equal weight” (or equal mass) of gold with silver, we can know that by observing the volume of water displaced in each case. An equal mass of silver will displace a different volume of fluid than that displaced by gold.

Answer:
d = kr
Explanation:
We know that the depth (d) varies directly with the amount of rain (r).
This means that as the amount of rain increases, the depth increases and vice-versa.
The depth would depend on r multiplied by a constant of variation (k)
Translating this into equation, we would get the following:
d = kr

If, for example, the usual price of the cycle is $4,100, and we want to know how much one could save by buying the cycle at $3,600, we must subtract $3,600 from $4,100:
$4,100
- 3,600
-----------
$500
