Region R is bounded by the lines y=4, x=6, the y-axis and the x-axis. Region R is rotated about the line y=-2. Find the volume of Region R after being rotated.

The volume of the region after being rotated is 603.186 unit³

Step-by-step explanation:

Here we have the shape formed by the region is that of a hollow cylinder with thickness 4 and length 6 with radius of opening at center = 2

Therefore, the volume is

πR²L - πr²L = πL(R² - r²)

Where:

R = Outer radius of the cylinder = 4 + 2 = 6

r = inner radius = 2

L = Length of the cylinder = 6

Therefore we have

Volume  = π×6×(6² - 2²) = 603.186 unit³.

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true

step-by-step explanation:

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
