Answer:
The volume of the cylinder is 3 times the volume of the cone
Step-by-step explanation:
The formula for the volume of the cylinder is given by :
.....(1)
Where
r and h are the radius and the height of the cylinder
The formula for the volume of the cone is given by :
...(2)
From equation (1) and (2),
So, the volume of the cylinder is 3 times the volume of the cone.
Given:
Total number of coins (Quarters and dimes) = 60
Total amount = $12.45
To find:
The number of quarters and dimes.
Solution:
Let x be the number of quarters and y be the number of dimes.
We know that,
1 quarter = 0.25 dollar
1 dime = 0.10 dollar
Total coins: ...(i)
Total amount: ...(ii)
From (i), we get
...(iii)
Putting this value in (ii), we get
Divide both sides by 0.15.
Putting x=43 in (iii), we get
So, the number of quarters is 43 and the number of dimes is 17.
Therefore, the correct option is b.
