An engineer is planning a new water pipe installation. The circular pipe has a diameter of d = 20 cm d=20 cmd, equals, 20, start text, space, c, m, end text. What is the area A AA of the circular cross section of this pipe? Give your answer in terms of pi

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:

$15.40 per mile

step-by-step explanation:

you have to round up to 4 because 6 is over 5 so you have to round the 3 up to 4
