Question

Volume and surface area of solid hemisphere are Numericall equal whatIs the diameter of a hemisphere

Answer 1

let the radius of the hemisphere be x units
volume of hemisphere= surface area of the hemisphere 
= 2/3πr^3 = 3πr^3
= 2/3r= 3
r= 92
d= 9 units
hence, the diameter of the hemisphere is equal to 9 units
