About the $x$ -axis (washer method):

$\displaystyle\pi\int_2^5\left(6^2-\left(\frac43x-\frac23\right)^2\right)\,\mathrm dx=\frac{16\pi}9\int_2^5(20+x-x^2)\,\mathrm dx=\boxed{56\pi}$

About the $y$ -axis (shell method):

$\displaystyle2\pi\int_2^5x\left(6-\left(\frac43x-\frac23\right)\right)\,\mathrm dx=\frac{8\pi}3\int_2^5x(5-x)\,\mathrm dx=\boxed{36\pi}$

About $x=7$ (shell method):

$\displaystyle2\pi\int_2^5(7-x)\left(6-\left(\frac43x-\frac23\right)\right)\,\mathrm dx=\frac{8\pi}3\int_2^5(35-12x+x^2)\,\mathrm dx=\boxed{48\pi}$

About $y=2$ (washer method):

$\displaystyle\pi\int_2^5\left((6-2)^2-\left(\frac43x-\frac23-2\right)^2\right)\,\mathrm dx=\frac{16\pi}9\int_2^5(5+4x-x^2)\,\mathrm dx=\boxed{32\pi}$

HELP ME OUT IM stoopid, I GIVE BRAINLIEST AND POINTS SUPER EASY

Alex17521 [72]

Answer:

Well I figure you would use a ratio. we are given one when comparing 240 lbs to 180 calories for each mile:

240lbs/180calories = 1 mile

we.are.given another when saying a person. burns 36 calories in 1 mile. we don't know weight so we will say x lbs:

x/36calories = 1 mile

since they both equal 1 mile we know they are equal:

240/180 = 1 = x /36

we can get rid of the 1 in between and say:

240/180 = x/36

let's reduce first fraction

8/6 = x/36

cross multiply:

8*36 = 6x

divide both sides by 6

8*6 = x

x = 48
