Question

Q2. The ratio of the radius of two spheres whose volumes are in the ratio 64:27 is
a)8:3 b)16:9 c)10:7 d)4:3​

Answer 1

Answer:

Step-by-step explanation:

let the radii of two spheres are R and r

their volumes are V and v

V/v =64/27 (given)

(4/3*πR³)/((4/3*πr³) = 4³/3³

after cancellation

R³/r³=4³/3³

(R/r)³=(4/3)³

therefore

R/r=4/3

R:r =4:3
