What is the surface area of the cylinder?
226.08 cm²
678.24 cm²
1,356.48 cm²
452.16 cm²
Answer:
452.16
Step-by-step explanation:
i got it right on test
The surface area of the cylinder is,
⇒ TSA = 452.16 cm²
We have to given that;
Height of cylinder = 6 cm
And, Diameter of cylinder = 12 cm
Hence, We get;
⇒ Radius of cylinder = 12 / 2 = 6 cm
We know that;
The formula for the total surface area of a given cylinder whose radius is r and height is h is,
TSA = 2πr (h + r)
Hence, We get;
TSA = 2πr (h + r)
TSA = 2 × 3.14 × 6 (6 + 6)
TSA = 37.68 × 12
TSA = 452.16 cm²
Thus, The surface area of the cylinder is,
⇒ TSA = 452.16 cm²

Kristin's Bikes rents bikes for $11 plus $2 per hour. Willie paid $23 to rent a bike. For how many hours did he rent the bike?
Define the variable, write an equation, and solve the equation.
Answer:
6
Step-by-step explanation:
Let x = number of hours.
Let y = cost.
The fixed cost is $11.
The cost per hour is $2.
For x hours, the cost per hour is 2x.
y = 2x + 11
23 = 2x + 11
12 = 2x
x = 6
Answer: 6

A chef takes c cartons of eggs from the refrigerator. Each carton contains 12 eggs. The chef wants to have a total of at least 50 eggs.
Answer: 5 cartons
Step-by-step explanation:
If the Chef wants to have a total of at least 50 eggs and each carton contains 12 eggs, divide 50 by 12 to find out the number of cartons needed and then round the number up:
= 50 /12
= 4.16
Round it up to the nearest 1:
= 5 cartons
This will ensure that there is at least 50 eggs because 5 * 12 = 60 eggs.
A charge of 100 elementary charges is equivalent to?
[tex] \sf{with \: explanation \: please}[/tex]
Answer: The charge is equal to 1.602*10^(-17) C
Step-by-step explanation:
The elementary charge (the smallest charge that exists) is the charge of one proton (or the magnitude of the charge of a single electron), and it is equal to:
c = 1.602*10^(-19) C.
Where C stands for coulombs,
Then a charge of 100 elementary charges is equal to 100 times the charge of a single electron, this is:
Charge = 100*( 1.602*10^(-19) C) = 1.602*10^(-17) C

a metal box that is in shape of cuboid has the following dimensions. the length is 9 inches, width is 2 inches and height is 1. 5 inches. find the total cost of silver coating the entire box if the cost of coating is $2.50 per Sq. inches
Given:
Length of a box is 9 inches, width is 2 inches and height is 1.5 inches.
The cost of silver coating is $2.50 per sq. inches.
To find:
The total cost of silver coating for the box.
Solution:
The total surface area of a cuboid is
[tex]A=2(lb+bh+hl)[/tex]
Where, l is length, b is breadth and h is height.
Putting [tex]l=9,b=2,h=1.5[/tex], we get
[tex]A=2(9\times 2+2\times 1.5+1.5\times 9)[/tex]
[tex]A=2(18+3+13.5)[/tex]
[tex]A=2(34.5)[/tex]
[tex]A=69[/tex]
So, the total surface area of the box is 69 square inches.
Cost of silver coating is $2.50 per sq. inches. So, the cost of silver coating for the box is
[tex]Cost=69\times 2.50[/tex]
[tex]Cost=172.50[/tex]
Therefore, the cost of silver coating for the box is $172.50.

50,000 joulesStep-by-step explanation:
total mass of people = 50× 5 = 250kg
height = 20m
force = mass × g = 250× 10 ( taking g= 10m/s²)
f= 2500Nwork done = force × distance
= 2500× 20

Laural had to find the average rate of change of f(x) over the interval from x = 6 to x = 10 using the table below.
What did she do wrong?
Step b is wrong. The slope is the change in y over the change in x.
Step b should be (18- 8)/( 10-6)
= 10/4
