Help Workers on a factory floor are painting one side of circular discs that will be placed on an assembly line. For every gallon of paint, a worker can paint an area that measures 1,256 square feet. If each disc has a radius of 2 feet, how many discs can they paint with one gallon of paint? Use 3.14 for π.

24+x=y

step-by-step explanation:

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:

2
