Find the volume of the cylinder

48π or 150.72

Step-by-step explanation:

The formula for the volume of a cylinder is V=πr^2h

Simply plug in the values:

V = π4^2 * 3

The answer, in terms of pi, would be:

V = 48π

However, if you use 3.14 for pi, it would be:

V = 150.72

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours

d is ur answer hopes this i dont really know how to explain it to u.
