Answer:
12.56 inches^2
Step-by-step explanation:
To solve this we use pi*r^2
Radius is diameter/2
so the equation is pi*2^2
pi*4
12.56 inches^2
Answer:
A≈12.57in²
Step-by-step explanation:
Using the formulas
A=πr2
d=2r
Solving forA
A=1/ 4πd^2=1/ 4·π·4^2≈12.56637in²
A≈12.57in²

Patrick is driving form Sydney to Canberra. He travels for 288km trip in 4 hours. What's his average speed?
Answers
Answer:
v = 72 km/h
Step-by-step explanation:
Given that,
The distance covered by the Patrick, d = 288 km
Time taken, t = 4 hours
We need to find the average speed of Patrick. We know that the average speed of an object is equal to the total distance covered divided by total time taken. Let it is v. So,
[tex]v=\dfrac{d}{t}\\\\v=\dfrac{288\ km}{4\ h}\\\\v=72\ km/h[/tex]
So, his average speed is equal to 72 km/h.

In a class of students, the following data table summarizes how many students have a cat or a dog. What is the probability that a student has a cat given that they do not have a dog? ( NO LINKS )
Answers
Given:
Number of students who has a cat and a dog = 5
Number of students who has a cat but do not have a dog = 11
Number of students who has a dog but do not have a cat = 3
Number of students who neither have a cat nor a dog = 2
To find:
The probability that a student has a cat given that they do not have a dog.
Solution:
Let the following events:
A = Student has a cat
B = Do not have a dog
Total number of outcomes is:
[tex]5+3+11+2=21[/tex]
The probability that a student has a cat but do not have a dog is:
[tex]P(A\cap B)=\dfrac{11}{21}[/tex]
The probability that a student do not have a dog is:
[tex]P(B)=\dfrac{11+2}{21}[/tex]
[tex]P(B)=\dfrac{13}{21}[/tex]
The conditional probability is:
[tex]P\left(\dfrac{A}{B}\right)=\dfrac{P(A\cap B)}{P(B)}[/tex]
[tex]P\left(\dfrac{A}{B}\right)=\dfrac{\dfrac{11}{21}}{\dfrac{13}{21}}[/tex]
[tex]P\left(\dfrac{A}{B}\right)=\dfrac{11}{13}[/tex]
Therefore, the probability that a student has a cat given that they do not have a dog is [tex]\dfrac{11}{13}[/tex].

The diameter of a truck wheel is 56.5 inches. What is the circumference of
the wheel?
Answers
Answer: 177.4999849 , or 56.5pi
Step-by-step explanation:
You simply divide the diameter by 2 to get the radius (28.25) and then plug into the circumference equation, 2*pi*r = Circumfrence.
Answer:
177.5 inches
Step-by-step explanation:
c = 2πr
d = r2
56.5/2=28.25
28.25x3.14= 88.705
88.705x2=177.41
Round, and you’ll get 177.5.

g(x) = x2 - 2x-3
Which of the following expressions is equivalent to f(x)/g(x), for x > 3
Answers
and
g(x)=x^2-2x-3
so you just need to divide f(x) by g(x)
Therefore:
f(x)/g(x) = (x^3-9x) / (x^2-2x-3)
and of course you need to factor these two function to see if some factor would cancel another

A farmer filled two cylindrical silos with wheat. The wheat in both silos has a density of 50 pounds per cubic foot. He had the wheat tested for protein content.
• The larger silo has a radius of 5 feet, a height of 10 feet, and the wheat is 12% protein.
• The smaller silo has a radius of 6 feet, a height of 6 feet, and the wheat is 15% protein.
The farmer states that the wheat in each silo contains over 5000 pounds of protein. Which of these is a correct evaluation of the farmer’s statement?
A.) He is correct about the protein content in both silos.
B.) He is incorrect about the protein content in both silos.
C.) He is correct about the protein content in the larger silo but incorrect about the protein content in the smaller silo.
D.) He is incorrect about the protein content in the larger silo but correct about the protein content in the smaller silo.

Step-by-step explanation:
volume of a cylinder = nr^2h
n = 3.14
r = radius
Volume of bigger cylinder = 3.14 x 5^2 x 10 = 785
total density = 50 x 785 = 39250
Protein content = 0.12 x 39250 = 4710
Smaller cylinder = 3.14 x 6^2 x 6 = 678.24
678.24 x 50 = 33912
33912 x 0.15 = 5086

Answers
Answer:
a. k = 27
b. k = 216
c. k = 0.216
Step-by-step explanation:
The value of the scale factor can be given by the following formula:
[tex]k = \frac{Final\ Volume}{Initial\ Volume}[/tex]
where,
Initial Volume = 8 cubic units
a.
Final Volume = 216 cubic units
Therefore,
[tex]k = \frac{216\ cubic\ units}{8\ cubic\ units}[/tex]
k = 27
b.
Final Volume = 1 cubic units
Therefore,
[tex]k = \frac{216\ cubic\ units}{1\ cubic\ units}[/tex]
k = 216
c.
Final Volume = 1000 cubic units
Therefore,
[tex]k = \frac{216\ cubic\ units}{1000\ cubic\ units}[/tex]
k = 0.216
