Answer:
Either one of these.
Step-by-step explanation:
volumepile=1/3 (PI r^2)h
but r=h/2, so
volume=1/12 PI h^3
dv/dt=10 ft^3/min
but dv/dt=1/12 PI 3h^2 dh/dt
solve for dh/dt
This assumes you mean by "altitude" the height. If you mean altitude as slant height, you have to adjust the fromula
_______________________________________________
given: r = h/2
V = (1/3)π r^2 h
= (1/3)π (h/2)^2 (h)
= (1/12) π h^3
dV/dt = (1/4)π h^2 dh/dt
for the given data ...
10 = (1/4)π(25)dh/dt
dh/dt = 10(4)/((25π) = 1.6/π feet/min

Answer:
Manisha spent 8 minutes and 24 seconds in a week climibing the stairs of her house.
Step-by-step explanation: (totally my work, not copied)
Convert seconds to minutes.
60x8=480
60x9=540
so, 8 minutes
Find the remaining seconds.
504-480=24
Add remaining seconds to minutes
24sec+8min=8min24sec
So hence, your answer is 8 Minutes and 24 Seconds
Manisha spent 8 minutes and 24 seconds in a week climbing the stair of her house.
Thanks!
