What is the volume of a right circular cylinder with a base diameter of 17.5 ft and a height of 24.5 ft?
use 3.14 for pi and round only your final answer to the nearest hundredth.
i don't even really need the answer. if someone could explain to me how to do it, that would be great! i looked up what i was supposed to do and got a coupe different answers. 

5889.95

Step-by-step explanation:

volume of a cylinder is the area of the base times the height. To find the area of the base it is Since they give diameter you need to find radius by dividing. 17.5 divided by 2 is 8.75. the area is then times height it is then, like they said, use 3.14 as pi. Round to get 5889.95

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

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:
