The can is 12 cm high and the diameter is 8 cm using the frmula v=ttr2h

Your spelled formula wrong

Given the volume of a cylinder V = pi(r2)h we simply plug in the numbers

The radius is half the diameter so r = 4cm

the height h is given as 12 cm

V = 3(42)(12) = 3(16)(12) = 576 cm3

Note:  Generally we would use 3.14 as the rounded value of p

step-by-step explanation:

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
