Answer:
3, 8
Step-by-step explanation:
We have been given that a right circular cone has a height of 12.2 cm and a base with a circumference of 18.5 cm. We are asked to find the volume of the cone to nearest tenth.
We know that circumference of circle is equal to
.



Now we will use volume of the cone formula to solve our given problem.






Upon rounding to nearest tenth, we will get:

Therefore, the volume of the given cube would be approximately 110.8 cubic centimeter.

Answer:
the answer is 4
Step-by-step explanation:
let x= length of the first piece.
second piece is 2x, right
third piece x+5, right
Total, in x-talk, is x + 2x + x+5 and that equals 21 feet, right.
Combine like terms: 4x + 5 = 21. Still with me?
So 4x = 16 (do you see why?)
So, what x must x be is 4
