Question

whole surface area of a solid hemisphere equal to the curved surface area of the solid sphere. write the ratio of lengths of radius of hemisphere and sphere.​

Answer 1

Answer:

2:√3

Step-by-step explanation:

Let the radius of the solid hemisphere be r1 unit and radius of the solid sphere be r2 unit. As per question, 3πr31=4πr22⇒r21r22=43⇒(rr2)2=(2√3)=2:√3. Hence the required ratio=2:√3.
