Question

a sphere has the same volume as a cylinder whose height is 3 times the radius of its cross section the ratio of the radii is​

Answer 1

Answer:

r1 : r2 =∛9/4

Step-by-step explanation:

given , volume of sphere = volume of cylinder

          4/3π(r1)³ = π(r2)²h and h = 3(r2)

         put the value of h .

         4/3π(r1)³ = π(r2)²{3(r2)}

         4/3π(r1)³ = 3π(r2)³

          [r1 / r2]³ = 9 / 4

          r1 / r2 = ∛9/4

Answer 2

Answer:

(9/4)/1/3
