Answer:
The volume of cylinder and the volume of a cone, have equal volume measurements. So, the answer is C).
Step-by-step explanation:
Cylinder:
-Use the formula for the volume of a cylinder. Use both the radius and height for the formula in order to solve and get the volume:

Cone:
-Use the formula for the volume of a cone and the radius and height for the formula and solve the formula to get the volume:


-Solve:





-So, according to the volume of a cylinder and the volume of a cone, They both have the same volume.
Cylinder:

Cone:

Answer:
The answer is B) -29.
Step-by-step explanation:
24.5 you take 3.5 and times it by 7 do get the distance.
4n² - 16n - 84 = 0
Multiply both sides by 1/4 :
n² - 4n - 21 = 0
Add 21 to both sides:
n² - 4n = 21
Complete the square by adding 4 to both sides:
n² - 4n + 4 = 25
(n - 2)² = 25
Solve for n :
n - 2 = ± √25
n - 2 = ± 5
n = 2 ± 5
Then n = 2 + 5 = 7 or n = 2 - 5 = -3.
