17.41- The formula for the volume of a cylinder is pi radius squared times height. (i.e. the area of the base times the height). You have pi 1.5 squared times height =123. Then you square it so you have 2.25 pi h= 123. then you have 7.065h=123. The you do algebra and you get 17.409, and round it to 17.41.
After solving the equation, you will find the correct answer to be C, <span>-7√8/8.

Answer:
nope
Step-by-step explanation:
they do not have the same exponent
no matter what the number with the x is, as long as the x's have the same exponent, they can be combined...
but in this problem such is not the case, because one x is to the power of 2 and the other is to the power of 1...
so, not in this problem...
You could sit down with several pencils and a whole pad of paper, and
divide Leda's mass by Europa's mass. But it's probably good enough
to provide an answer that's correct to 2 or 3 significant figures, and
there's a much easier way to do that:
Leda's mass . . . . approx. 1.094 x 10¹⁶
Europa's mass . . . . approx. 4.8 x 10²²
Leda's mass is about (1.094 x 10¹⁶) / (4.8 x 10²²) of Europa's mass.
(1.094 x 10¹⁶) / (4.8 x 10²²) = 2.28 x 10⁻⁷
Leda's mass is approx. <em>0.000 000 228</em> of Europa's mass.
