Answer: V=πr^2h=π·4^2·8≈402.12386cm^2
Surface Area of a cylinder 2(π•r²)+(2π•r)•h
So
If the diameter is 8 then the radius is 4. the height is 5.
so you have, 2(3.14•4²)+(2•3.14•4)•5
solve. PEMDAS
Parentheses & Exponents first.
2(3.14•16)+(2•3.14•4)•5
2(50.24)+(6.28•4)•5
2(50.24)+(25.12)•5

- The zeros of the function are 0 and 2
- The multiplicity is the power to which the factors are raised. The multiplicities of the function are 1 and 3.
<h3>Zeros and multiplicities of functions</h3>
Given the function 
The zeros of the function is at the point where y = 0

Hence the zeros of the function are 0 and 2
The multiplicity is the power to which the factors are raised. The multiplicities of the function are 1 and 3.

Answer:
18x = 7.2
x =.4
Step-by-step explanation:
Let x = the weight of one box
We have 18 boxes that weigh 7.2 lbs
18x = 7.2
Divide each side by 18
18x/18 = 7.2/18
x =.4
6x - 2x = 16
4x = 16 |divide both sides by 4
<h3>x = 4</h3>
