A piece of string 8 inches long is cut into two pieces, one of which is of length x inches. If this piece is made into the circumference of a circle, and the other piece is made into the circumference of a square, then the combined area of the circle and square, as a function of x, is:

answer: it's upside down and i can't read it

step-by-step explanation:

the answer is 62.8 cubic units

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:
