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 /$\sqrt{3\\}$

Step-by-step explanation:

Let radius of hemisphere= R

Let radius of sphere = r

Whole surface area of hemisphere= 3pi(R)^2

Curved surface area of sphere= 4pi(r)^2

Since Both are equal

Therefore, 3pi(R)^2 = 4pi(r)^2

So, (R/r)^2 = 4/3

So, R/r = 2 /$\sqrt{3\\}$
