Given:
The diameter of a sphere is 19 cm.
To find:
The volume of the sphere.
Solution:
We have,
The volume of the sphere is
where, r is radius.
Putting 
in the above formula.
Therefore, the volume of the sphere is 3592.8 sq. cm.
It’s 75.4 , I’m not sure abt those answers up there
The area is what is given. Find the base and height and multiply that. Since, you done that, you simplify if any fraction is there. Then, you have an answer!
Here is the solution to the given problem above.
Given that for an 8 pound bag of tomatoes costs $5.60, we would want to know how much will it be for 11 pounds. First, we should know how much does it cost per pound. So 5.60 divided by 8 is 0.7. So per pound of tomatoes costs $0.7. Now to know how much for 11 pounds, we multiply 0.7 by 11 and we get $7.70. The correct answer therefore would be option C. $7.70. Hope this answer helps.
