Please help me what is the answer I need help fast

the first step is to convert the diameter into a radius measure by using the formula d=2r

when we solve the formula the radius is calculated to be 1.5

use the surface area formula above and your height and radius measurement to find out the area of sheet metal you would need.

2pi(1.5)^2+2pi(1.5)(5)

using 3.14 for pi this equates to 61.23in^2

Step-by-step explanation:

This car follows a line, hence its motion can be modeled by the Line equation.

In fact, we already have two points of the line, if we call the time in hours and the traveled distance in miles:

Point 1:

Since we are told the car's initial position is 300 miles in the time 0 h

Point 2:

Since we are told the car's final position is 180 miles after 3h

Let's find the Slope :

 This is the slope of the line

Now, the equation of the line is:

We already know the slope, now we have to find the intersection point with the y-axis () with any of the given points. Let's choose Point 1:

Isolating :

Then, the equation of the line is:
