Answer:
8:24
Step-by-step explanation:
since 1:3 is already given to you
and 8:_ needs to be found
you know that the new ratio is 8 times bigger than the original one
multiply 1 by 8 and you get 8
multiply 3 by 8 and you get 24
check the picture below.
notice, both pairs of opposite sides are parallel.
Answer:
Let S be the total surface area. Then
h = ( S - 2 Pi r^2) / ( 2 Pi r)
Discussion:
Let S be the total surface area. Then
S = 2Pi r*h + 2 Pi r^2 => subtract 2 PI r^2 from both sides
S - 2 PI r^22 = 2 PI r*h => divide both sides by 2 PI r
h = ( S - 2 Pi r^2) / ( 2 Pi r)
