Answer:
The volume of a cone is 1/3 of the volume of the cylinder.
Step-by-step explanation:
The formula for a cylinder is:
V = bh
For a cone:
V = 1/3(bh)
If the radius of both are the same, then the area of the base is the same. The height is also constant, therefore:
The volume of a cone is 1/3 the volume of the cylinder.
--------------------------
Example to prove:
Given, radius 2 and height 15:
Cylinder: V = bh (b = πr²)
V = 4π × 15
V = 60π u³
Cone: V = 1/3 (bh)
V = 1/3 (4π × 15)
V = 20π u³
Hi there!
πd = Circumference of th' circle
![\dfrac {22}{7}](https://tex.z-dn.net/?f=%5Cdfrac%20%7B22%7D%7B7%7D)
× d = 15 ft
d = 15 ×
![\dfrac {7}{22}](https://tex.z-dn.net/?f=%5Cdfrac%20%7B7%7D%7B22%7D)
d =
![\dfrac {105}{22}](https://tex.z-dn.net/?f=%5Cdfrac%20%7B105%7D%7B22%7D)
d = 4. 77
Hence, the required dia-meter = 4. 77

Step-by-step explanation: brobro
I see choice (A) is missing, so I am giving you two solutions for you to understand and decide which one applies:
(1) Final balance with compound interest - meaning every year you add the year's interest to the principal and earn interest on the increased amount, etc. This is the actual case in real banks:
principal amount is $425 at (annual) interest rate 4.5%
interest amount for 1 year $19.13
Now, use the formula for compound interest
total balance = principal*(1+interest rate)^year
![\$425\cdot(1.0475)^4= \$511.68](https://tex.z-dn.net/?f=%5C%24425%5Ccdot%281.0475%29%5E4%3D%20%5C%24511.68)
So the amount after 4 years with compound interest should be $511.68
(2) the silly way: earn interest of $20.1875 every year and keep it separately (not earning additional interest). That'll make 425+4*20.1875=$505.75 which is answer (C)
so if your (A) matches my solution (1) then go with that. If not, choose (C).
