Deriving a Formula for Volume of a Cylinder
Complete the derivation of the formula for a cylinder
whose height is equal to its radius.
Suppose the height of a cylinder is equal to its radius.
The cylinder can fit inside a square prism, as shown
below
The cross-sectional areas are still the same and the ratio
of the area of the circle to the area of the square is still
The prism's volume is the area of the base,
vtimes the height,
Since the ratio of the areas is 4 , then the volume of
the cylinder is vtimes the volume of the prism.
V = 4 (473), or
2r

$4

step-by-step explanation:

$30×5=$150

$150 minus $130=$20

$20÷5=$4.

hope to and hope that my answer is brainliest.(follow me )

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)  

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula

you just switch the numbers basically so it would be 3/17
