Answer:

Step-by-step explanation:

The slope is 3/2

the y-intercept is -4.5

so the equation is y = 3/2x + (-4.5)

(it’s a plus because the slope is positiv, meaning the line goes upwards to the right.)

the diameter of a cone-shaped container is 4 inches, and its height is 6 inches .How much grater is the volume of a cylinder-sha

sveticcg [70]

The radius r used in below equations would equal 2in because it is half the given diameter of 4in.
The volume of the cone would be
$V = \frac{1}{3} \pi r^2h \\ \\ V = \frac{1}{3} \pi (2in)^2(6in) = 8 \pi\ in^3$

The volume of a cylinder with the same dimensions would be
$V = \pi r^2h \\ 
V = \pi (2in)^2(6in) = 24 \pi in^3$

The cylinder is 24 - 8 = 16 cubic inches greater.
