Ratios and fractions are interchangeable (for the most part). A fraction is a type of ratio. And we've all worked with fractions before, so that's what we'll do here.
I can say that the ratio 3:1 is the same as the fraction 3 / 1. Using that fraction, it is fairly easy to find equivalent fractions.
3 / 1 = 6 / 2 = 9 / 3 = 30 / 10
...And so on
Another example, 5:6 = 5 / 6.
5 / 6 = 10 / 12 = 15 / 18 = 30 / 36
To find equivalent fractions, all you need to do is multiply both the numerator and denominator by the same number. As long as that number is the same (and your multiplication is correct), then the new fraction will be equivalent to the original.
Hope this helps!
Answer:
r = 4.417
Step-by-step explanation:
in order to calculate the radius of a sphere
given that
volume of sphere = 361
π = 3.14
radius = ?
recall that the volume of a sphere = 4/3 πr³
361 = 4 /3 × 3.14 × r³
361 = 12.56r³/3
cross multiply
361 × 3 = 12.56r³
1083 = 12.56r³
divide both sides by 12.56
1083/12.56 = 12.56r³/12.56
86.226 = r³
find the cubic root of both sides
r = ∛86.226
r = 4.417
therefore the radius of the sphere is evaluated to be 4.417
