A cone has a radius of 5 ft and a height of 15 ft. It is empty and is being filled with water at a constant rate of 15 15 ft 3 ft3 / sec sec . Find the rate of change of the radius of the surface of the water when the radius of the surface of the water is 2 2 ft. (You must also include the units)

Step-by-step explanation:

From the question we are told that:

Radius

Height

Rate

Surface Radius

Generally the equation for Volume is mathematically given by

Since radius to height ratio gives

Therefore

Generally the equation for Change of Volume is mathematically given by

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

no its the same as every other grade
