उत्तर
The ratio of the total surface area of a hemisphere and a sphere of same radius is 3:4.
Explanation:
The total surface area of a hemisphere of radius r is 3πr2, and the total surface area of a sphere of the same radius is 4πr2. Therefore, the required ratio is `3πr2/4πr2 = 3/4` which equals 3:4.
