Spherical 63214

The gas tank consists of a 16m high cylinder with a diameter of 28m, which is closed at the top by a spherical canopy. The center of the spherical surface lies 4m below the bottom of the cylinder. Please calculate the spherical surface's radius and the canopy's height.

Correct answer:

r =  28.2843 m
h =  24.2843 m

Step-by-step explanation:

h=16 m R=28 m y=4 m  r2=R2+y2  r=R2+y2=282+42=20 2=28.2843 m
h=ry=28.28434=24.2843 m
