calculate the volume of a cylinder of diameter 5.93cm and length 10cm in log an atilog
Answer:
V=22/7×r^2×h
=22/7×(5.93/2)^2×10
=276.26cm
Step-by-step explanation:
Use the equation V=22/7×r^2×h
V=volume
r=radius
h=height
Substitute the values for r and h, then find the value for V
The volume of cylinder is 276.04 cm³.
what is Volume of Cylinder?The density of a cylinder is determined by its volume, which represents how much material may be immersed in it or carried inside of it. The formula πr²h, where r is the radius of the circular base and h is the height of the cylinder, determines the volume of a cylinder.
Given:
d= 5.93
h= 10cm
r= 5.93/2
Now, volume of cylinder
= πr²h
= 3.14 x 5.93/2 x 5.93/2 x 10
= 31.4 x 8.7912
= 276.04 cm³
Hence, the volume of cylinder is 276.04 cm³.

On a trip to see his best friend Daniel begins with 12.8 gallons of gas in the tank.
He stops after driving for 2 hours and fills the tank to capacity with 14.4 gallons.
When Daniel arrives at his friend's house, he has 3.7 gallons of gas left.

What is f(4) for the function f(x) = 6x +3?
f(4)=0
The value of function f(4) is 27.
It is required to find the value of function f(4).
What is function?
A function is defined as a relation between a set of inputs having one output each. function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.
Given that:
The function is
f(x) = 6x +3
Now put the value x=4 in the given function, we get
f(4)=6(4) +3
= 24+3
=27
f(4)=27.

Isaiah is mowing lawns for a summer job for every mountain Charlie charges an initial fee of $10 plus $6 dollars for each additional hour
1. write an equation in slope intercept form
2. how much money does he make after working one job for four hours
Answer:
y = 6x + 10
Isaiah makes $34.00 after working for 4 hours.
Step-by-step explanation:
Slope intercept form is y=mx+b
In this situation the equation would look like so, x = amount of hours:
y = 6x + 10
To solve for how much Isaiah earns after 4 hours plug in 4 instead of x.
y = 6(4) + 10
y = 24 + 10
y = 34
Isaiah makes $34.00 after working for 4 hours.

Both positive
Both negative
One is positive and other is negative
None
Answer:
both negative
Step-by-step explanation:
Descartes rule of signs tells us how many positive and negative real roots a polynomial has.
Given
f(x) = x² + 5x + 6 , with signs
+, +, + ← no change of signs, thus no positive zeros
f(- x) = (- x)² + 5(- x) + 6 = x² - 5x + 6 , with signs

Mr. Richard plans to take 25 students on a school trip. They plan to go to Zoo. The bus fee is $100 for the entire trip. Entrance fee is $2.50 per person. How much should each student pay? Note: Mr. Richard does not need to pay.
Answer:
$162.50
Step-by-step explanation:
+$100
25x2.50= $62.50
+$62.50
100+62.50=162.50
Answer:
Each student should pay $6.50
Step-by-step explanation:
The question is not very clear.
If Mr. Richard has to pay to enter:
Total cost = $100 + ($2.50×26) = $165
Cost per student = [tex]\frac{165}{25}[/tex] = $6.60
Each student should pay $6.60
If Mr. Richard doesn't have to pay to enter:
Total cost = $100 + ($2.50×25) = $162.5
Cost per student = [tex]\frac{162.5}{25}[/tex] = $6.50
Each student should pay $6.50
