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.
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.
A = (1/2)(x)(y)
Let x = diagonal 1
Let y = diagonal 2
The product of xy = 144.
This means that x = 12 and y = 12.
So, 12 • 12 = 144
Each diagonal is 12 feet.
Prove:
72 feet = (1/2)(12)(12) feet
72 feet = (1/2)(144) feet
72 feet = 72 feet
The correct answer is 4.6
First, since on pemdas subtraction it addition could come first depending on the order, subtract b from a. the add a2, ab, and b2 together. then multiply your two sums
