The hose is 2 inches in diameter. What circumference does the plug need to be?
Remember to type just a number, do not add units. *

6.28

Step-by-step explanation:

This problem bother on the mensuration of flat shapes, a circle.

Volume v =

Diameter d=  

Radius r =  

Since we are required to solve for the circumference of a circle

The expression for the circumference of a circle is given as

The question insist that we type just a number hence the circumference of the plug is 6.28

answer

see attachment

explanation

the given function is

this function has y-intercept at

-4 and a slope of 2.

note that, the graph has a positive slope.

the graph that represents this function is the straight line that moves upward from left to right.

the graph touches the y-axis at -4.

the correct choice is the graph shown in the attachment.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
