Answer: Just apply the formula
Step-by-step explanation:
The equation for volume of a cone is:
The radius is the line that creates a 90 degree angle with the height
The height goes from the base to the tip of the cone.
I recommend leaving Pi as it is and plugging the rest of the numbers first.
Then at the end multiply by 3.14 and round at the end.
This way, it is easier to avoid calculation errors.
Answer:$21.207 or $21.21
Step-by-step explanation:
You would take $24.95 *85% (that is how much you are going to pay) and the result is your answer
x = total amount split between Adam and Tom.
since we know the total amount split between both in a 18 : 17 ratio is "x", let's divide "x" by (18 + 17) and distribute accordingly to get the amount of each.

Answer:
128 feet squared
Step-by-step explanation:
you multiply 4 by 4 to get 16 ,
then you multiply 7 by 4 and get 28,
also multiply 28 by 4 and get 112 ,
finally add 112 and 16 to get 128
