A company that manufactures storage bins for grains made a drawing of a silo. The silo has a conical base, as shown below:
2 answers:
The volume of the silo is (π×2²×8.5+ ×π×2²×(13-8.5)) cube ft.
Step-by-step explanation:
Given,
The silo consists of a cylinder and a cone.
The diameter of the silo = 4 ft
The length of the cylindrical part = 8.5 ft
The entire length of the silo = 13 ft.
To find the volume of the silo.
The volume of the silo = the volume of cylinder + the volume of the cone
Formula
r be the radius and h be the height
- The volume of cylinder = πr²h
- The volume of cone =
πr²h
Now,
The radius of the cylinder = 2 ft.
Height = 8.5 ft
Volume = π×2²×8.5 cube ft
Again,
The radius of the cone = 2 ft
Height = 13-8.5 = 4.5 ft
Volume = ×π×2²×4.5 cube ft
Hence,
The volume of the silo = (π×2²×8.5+ ×π×2²×(13-8.5)) cube ft.
The correct option is B.

The amount of each of the 6 payments will be $41.50
Step-by-step explanation:
Given,
Cost of bike including taxes = $349
Down payment = $100
Amount left to pay = Cost of bike - Down payment
Amount left to pay = 349 - 100
Amount left to pay = $249
She agrees to pay in 6 equal payments, therefore, we will divide the total amount to pay by 6.
Amount to pay for one month =
Amount to pay for one month =
The amount of each of the 6 payments will be $41.50
