Answer:

Step-by-step explanation:
Given


Required
The volume of the sphere
This is calculated as:

So, we have:


This gives:


Given:
Height of man = 6 ft
Height of man's shadow = 11 feet
Height of building's shadow = 139 feet
To find:
The height of the building.
Solution:
We know that the heights of the objects and there shadows are always proportional.

Let x be the height of the building.

Multiply both sides by 139.




Therefore, the building is 75.8 feet long.

Convert the dose into mg / lb
1 lb = .45 Kg
so the does = 6 * .45 = 2.7 mg/lb
so the daily dose of the patient is 93 * 2.7 = 251.1 mg
injections are available in 50mg per mL
to calculate the daily dose in mL 251.1 / 50 = 5 mL
