The formula for the volume of a right cylinder is V = (pi)r^2h. Find the rate of change of the volume when r = 2 inches if dr/dt = 1/8 in./min and h = 5r. Show all your work.

The volume is increasing at a rate of 15π/2 squared inches per minute.

Step-by-step explanation:

The formula for the volume of a right cylinder is:

We want to find dV/dt when r = 2, dr/dt = 1/8 in/min, and h = 5r.

Since h = 5r:

Differentiate both sides with respect to t:

Since r = 2 and dr/dt = 1/8:

So, the volume is increasing at a rate of 15π/2 squared inches per minute.

answer:   x*94 +688*6   = 267*100

94x+4128=26700    

94x=22572     /94

x=240.128

134.6 us dollars

step-by-step explanation:

1 us dollar = 1.33 canadian dollars

so, 150 us dollars = 150 × 1.33 = $199.5.

in canada, the money mitchell spent = 20 canadian dollars.

remaining canadian dollars with him = 199.5 - 20 = 179.5.

after mitchell returned to us, he exchanged the remaining canadian dollars to us dollars.

179.5 canadian dollars = 179.5 × 0.75 = 134.6 us dollars.
