30 points the radius of a 10 inch right circular cylinder is measured to be 4 inches, but with a possible error of ±0.1 inch. use linear approximation or differentials to determine the possible error in the volume of the cylinder. include units in your answer.

dV = ±8π in³

Step-by-step explanation:

You're given the height, radius, and change in radius (the radius error, dr).

You're asked to find the change in volume (error of the volume, dV).

First write down the equation for the volume of a cylinder.

Derive the volume with respect to the radius (dV/dr) so that you can solve for their changes.

Rearrange the equation to solve for dV.

Plug in your given values.

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

step-by-step explanation:

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
