Step-by-step explanation:

The question is incomplete. Here is the complete question;

'What is the exact volume of the cylinder? 32π in³ 64π in³ 128π in³ 512π in³ Cylinder with radius labeled 4 inches and height labeled 8 inches'

Volume of a cylinder = πr²h

r is the radius of the cylinder

h is the height

Given r = 4in

h = 8in

Volume =  π(4)²*8

volume of the cylinder = 16π*8

volume of the cylinder = 128πin³

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
