The ratio of the volume of two spheres is 27:125. What is the ratio of lengths of the radii?

3:5

Step-by-step explanation:

V1 / V2 = 27 / 125

Volume of a sphere = 4/3πr³

(4/3πr₁³) / (4/3πr₂³) = 27/125

r₁³ / r₂³ = 27/125

r₁ / r₂ = [3√(27)] / [3√(125)]

r₁ / r₂ = 3/5

r₁:r₂ = 3:5

The ratio of the length of their radius is 3:5

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

i just took the test, the correct answer is .. 31.5 in.
