Answer:
Step-by-step explanation:
Given :
- Diameter of a drum = 20 inches
- Deep ( height ) of the drum = 16 inches
- π = 3.14
To Find:
The volume of the drum.
Solution:
We all know that drum is cylindrical.So we'll use the formulae of the volume of cylinder,to find its volume.
Where,
- r = radius
- h = height (deep)
- π = 3.14
The value of radius ain't given,but the diameter is given.We can use the formulae of radius.
- D = diameter
Substitute the value of diameter:
Hence,the radius is 10.
So we could now use the formulae of the volume of cylinder:
- π = 3.14
- r =10 in
- h = 16 in
<em>[Firstly bring the answer in terms of π then plug π = 3.14 and then simplify.]</em>
<u>Hence, we can conclude that:</u>
The volume of this drum is 5024 in^3.
