Answer:
Volume V= πr²h
Volume V= base * height
Step-by-step explanation:
Volume is the capacity of an object which is obtained by multiplying area with height. Volume of a cylinder is generally calculated by two formulas.
Volume of a cylinder V= πr²h Where r is the radius and h is the height
Volume of a cylinder V= base * height
If we analyse the two formula keeping in mind that the base of the cylinder is circular . The area of a circle is given by πr². In this first formula we can find the area of the base by applying the formula of the circular region. Volume is measured by multiplying length , breadth and height, or area with height. In both the formulas given above we find the area and then multiply with the height.
Answer: means you can switch up the numbers
Step-by-step explanation:
so Commutative Property means you can switch up
the numbers not the sign for example.
4 × 3 × x
4 × x × 3
3 × x × 4
x × 3 × 4
x × 4 × 3
if you look at all these! they just switch
this is easier like 4x5=20 in communicative property it would be 5x4=20
Hope this helps :)
Answer:
10.429% exceed
Step-by-step explanation:
expected:
150x [100+40]/100=210 parents were expected on first night
210x60/100=126 parents expected on the second night
210+126=326 expected
percentage difference=
210+150=360
360/326 x 100=110,429%
110,429%-100%=10,429% exceed
Answer:
x = -1
General Formulas and Concepts:
<u>Pre-Alg</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
5x - (x + 4) + 1 = 3 - 2(x + 6)
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute: 5x - x - 4 + 1 = 3 - 2x - 12
- Combine like terms: 4x - 3 = -2x - 9
- Add 2x on both sides: 6x - 3 = -9
- Add 3 to both sides: 6x = -6
- Divide both sides by 6: x = -1
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: 5(-1) - (-1 + 4) + 1 = 3 - 2(-1 + 6)
- Parenthesis (Add): 5(-1) - 3 + 1 = 3 - 2(5)
- Multiply: -5 - 3 + 1 = 3 - 10
- Subtract: -8 + 1 = -7
- Add: -7 = -7
