The volume of a sphere is equal to (4/3)pi*r^3
The volume of your sphere is then (4/3)*pi*r^3 = (4/3)*3.14159265*18^3 = 24429.024 cubic units. That is not one of the answer choices. The closest choice appears to be D.
Supplementary angles are those angles whose sum of the measures of angles is 180 degrees.
Observe the figure clearly.
1. 
are supplementary angles.
2. 
are supplementary angles.
3. 
are supplementary angles.
4. 
are supplementary angles.
5. 
are supplementary angles.
6. 
are supplementary angles.
What kind of question is that? That’s a statement.
Answer:
did that first one its false
A= 53, B= 100, C= 27 (the last option)
BC is the longest side because it is opposite the largest angle ( not true)
The answer is : Prism
hope this helps !
