Question

Help! An empty cup in the shape of a cylinder (pictured below) is being filled with water.

Answer 1

Answer:

( About ) 90%

Step-by-step explanation:

We are given the table below;

Number of seconds | Amount of water

              0                 |             0

              3                 |             75

              6                 |             150

Now from this table we see that the rate change is that for every 3 seconds of difference, the amount of water increases by 75 cm^3;

If that is so, the amount of water after 7 seconds is 150 + ( 75 / 3 ), provided the difference in seconds between 6 and 7 is 1 / 3rd that of the difference between 0 and 3, or 3 and 6;

150 + ( 75 / 3 ),

150 + 25,

175 cm^3

Now let us compute the total volume of this cylinder, as such;

πr^2 * height,

π * ( 3 )^2 * 7,

9 * π * 7,

Volume of can ⇒ 197.82 cm^3

175 / 197.82 = 0.9 = Solution; 90%
