Suppose that a sphere with radius 5a has the same volume as a cone of radius 3a. What is the height of the cone? Give your answe
r in terms of a. Use the formulas and for the volumes of a sphere and cone respectively.
2 answers:
Volume of the sphere: [4/3]π (r^3) = [4/3]π(5a)^3 = [4/3]π*125a^3 =
Volume of the cone: [1/3]π(r^2)H = [1/3]π(3a)^2 * H = 3πa^2 * H
Volumen of the sphere = Volumen of the cone =>
[4/3]π*125a^3 = 3πa^2 * H => H = [500/9]a = 55.55 a
Answer: its 500/9a : took the test got it right! hope this helps(:

Answer:
5^14
Step-by-step explanation:
We use the laws of indices:
When there is a power outside the bracket multiply the powers.
(a^m)^n=a^m×n
So (5^7)^2=
5^7×2
