Given:
A figure of combination of hemisphere, cylinder and cone.
Radius of hemisphere, cylinder and cone = 6 units.
Height of cylinder = 12 units
Slant height of cone = 10 units.
To find:
The volume of the given figure.
Solution:
Volume of hemisphere is:
Where, r is the radius of the hemisphere.
Volume of cylinder is:
Where, r is the radius of the cylinder and h is the height of the cylinder.
We know that,
[Pythagoras theorem]
Where, l is length, r is the radius and h is the height of the cone.
Volume of cone is:
Where, r is the radius of the cone and h is the height of the cone.
Now, the volume of the combined figure is:
Therefore, the volume of the given figure is 2110.08 cubic units.

Answer:
Probabilty of not poor= 0.75
Step-by-step explanation:
total of 11332 bonds.
7311 are good risk.
1182 are medium risk.
Poor risk
= total risk-(good risk+ medium risk)
= 11332-(7311+1182)
= 11332-8493
= 2839.
Poor risk = 2839
Probabilty that the ball choosen at random is not poor= 1 - probability that the ball is poor
Probability of poor = 2839/11332
Probabilty of poor= 0.2505
Probabilty that the ball choosen at random is not poor= 1- 0.2505
= 0.7495
To two decimal place= 0.75
