A grain silo is shown below:

Grain silo formed by cylinder with radius 6 feet and height 168 feet and a half sphere on the top

What is the volume of grain that could completely fill this silo, rounded to the nearest whole number? Use 22 over 7 for pi.

If this helps feel free to Make this your Brainliest answer!

Find the volume of the bottom and top separately and then add them.

Cylinder volume is the area of the bottom times the height

(22/7)(5^2)•175=13750 ft^3

The volume of a sphere is

V=(4/3)(22/7)r^3

where r is the radius. Here that's also 5 since it fits on the cylinder.

Also we only want half the sphere so use

V=(2/3)(22/7)•5^3=261.9 ft^3

Which we round upto 262.

Now add the parts together

13750+262=14,012 ft^3

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.

step-by-step explanation:

first you will have to convert 3/4 into a decimal

which is .75

then you will have to divide 1.5 by .75

which is 2

no you have to divide
