Answer 1

Given:

Workers on factory floor are painting one side of a circular discs that will placed on an assembly line. For every gallon of paint, a worker can paint an area that measures 1256 ft.². Each disc has a radius of 2 feet.

Required:

How many disc can they paint with 1 gallon of paint?

Step-by-step explanation:

We have radius of disc 2 feet and

`Area\text{ of disc = }\pi r^2`

Now, given every gallon of paint, a worker can paint an area that measures 1256 ft square.

So, with 1 Gallon of paint no. of discs can be paint is

`\begin{gathered} =(1256)/(3.14*4) \\ =(1256)/(12.56) \\ =100 \end{gathered}`

Answer:

Hence, 100 discs can be paint with 1 gallon.
