A sphere of radius 49 cm is divided into 4 equal parts from center.
What would be the total surface area of one of such quarter sphere?

OPtion

1) 15092 m^2
2) 10061.33 m^2
3) 22638 m^2
4) 7546 m^2
5) 16092 m^2
6) 1.0061 m^2
7) 1.5092 m^2
8) 2.2638 m^2
9) 7.546 m^2
10) None of these

Solution

Total Surface Area of quarter sphere = (1/4) 4*Pi*r^2 + (1/2) Pi*r^2 + (1/2) Pi*r^2 = 2 Pi*r^2

Answer = 2* Pi * 49^2 = 15092 cm^2 = 1.5092 cm^2
