Find the volume of the cylinder in terms of pi h = 6 in. and r = 3 in. A 54π in.3 B108π in.3 C324π in.3 D 27π in.3

Orlov [11]

Answer:

Option A. $54\pi\ in^{3}$

Step-by-step explanation:

we know that

The volume of the cylinder is equal

$V=\pi r^{2}h$

where

r is the radius of the base of cylinder

h is the height of the cylinder

we have

$r=3\ in$

$h=6\ in$

substitute

$V=\pi (3)^{2}(6)$

$V=54\pi\ in^{3}$

The manager of the motor pool wants to know if it costs more to maintain cars that are driven more often. Data are gathered on e

Liula [17]

Answer:

b. There's no statistically significant linear relationship between the number of miles driven and the maintenance cost

Step-by-step explanation:

The p-value for the slope estimate show us how strong is the certainty that there are a linear relationship between both variables. In this case, the p-value for the slopes shows if there is a significant relationship between the number of miles driven and the maintenance cost.

If we have a high p-value like 0.7 we can said that there is no certainty in the linear relationship. it means that there's no statistically significant linear relationship between the number of miles driven and the maintenance cost.
