Answer:
Step-by-step explanation:
Given
Represent radius with r and height with h
when
Express radius in terms of height
First, we need to determine the volume of the cone in terms of height.
Substitute
Differentiate both sides w.r.t time (t)
Solve for
At this point, and
So, we have:
Hence:
The rate is
First turn any mixed numbers into improper fractions. 1 3/4 would be 7/4. Becuase you multiply the whole number by the denominator and then add the numerator.
So now you have 7/4 divided by 2/5. Whenever you divide, you flip the 2nd fraction upside down... known as the reciprocal. And after that you <em>multiply </em>the first number by the upside down 2nd number.
So now you have 7/4 X 5/2. When multiplying, just multiply the numerators across and the denominators across. As your answer, you get 35/8 or 4 3/8.
