Step-by-step explanation:
To find the surface area of a cone, one uses the following formula,
[tex]A=(\pi)(r)(r+\sqrt{h^2+r^2}})[/tex]
Where (r) is the radius of the base of the cone, and (h) is the height of the cone, ([tex]\pi[/tex]) represents the numerical constant (3.1415...). In order for this formula to work, one needs the height of the cone. This can be found using the Pythagorean theorem. One can form a right triangle with the base's radius, the side length, and height of the cone, then solve for the height of the cone. The Pythagorean theorem states the following,
[tex]a^2+b^2=c^2[/tex]
Substitute,
[tex]a^2+(1)^2=(5.1)^2[/tex]
Simplify,
[tex]a^2+1=26.01[/tex]
Inverse operations,
[tex]a^2=25.01\\a\approx5[/tex]
Now one can use the formula to find the surface area of a cone, substitute in the given values, and solve,
[tex]A=(\pi)(r)(r+\sqrt{h^2+r^2}})[/tex]
Substitute,
[tex]A=(\pi)(1)(1+\sqrt{5^2+1^2}})[/tex]
[tex]A=(\pi)(1+\sqrt{25+1})\\A=\pi(1+\sqrt{26})\\A\approx 19.16[/tex]

d. Find m∠ABE.
e. Find m∠ABF.
f. Find m∠EBF. How did you find this?
f. . Find m∠FBC. How did you find this?
Answers
a. <FEB and <AEB are alternate interior angles
b. AC and DG are parallel lines
c. EB and BF are the transversals
d. <ABE and <FEB are alternate interior angles, meaning that their angle measures are congruent, thus <ABE = <FEB = 45
e. <GFB and <ABF are alternate interior angles, meaning that their angle measures are congruent, therefore <ABF = 110
f. <GFB is a remote angle to triangle EBF. Remote angles are formed when one extends one of the sides of a triangle, the remote angle is found between the extension of the side and a side of the triangle. The remote angles theorem states that the sum of the two non-adjacent angles equals the remote angle. Applying this here one can state the following,
<FEB + <FBE = <GFB
45 + <FBE = 110
<FBE = 65
f. <FBC and <GFB are same-side interior angles, this means that the two angles are supplementary, their angle measures add up to 180. Apply this property here,
<GFB + <FBC = 180
110 + <FBC = 180
<FBC = 70

Owen and Jesse go to a restaurant for breakfast. A 7% sales tax is applied to their $21.60 bill. If Owen and Jesse add a 15% tip after the tax is applied, what is the total cost, including tip?
Answers
Answer:
The total cost is 26.6 dollars
Step-by-step explanation:
Given
The total bill of the breakfast = $ 21.60
Sales tax = 7% of the total bill value
Total bill after adding the 7% sales tax
$ 21.60 + 7% of $ 21.60
[tex]21.60 + \frac{7}{100} * 21.60\\21.60 + 1.512\\23.112[/tex]dollars
After adding 15% of the tip values to the payable amount of $ 23.112, the total bill becomes
$ 23.112 + 15% of $ 23.112
[tex]23.112 + 3.4668 = 26.5788[/tex]
The total cost is 26.6 dollars

Step-by-step explanation:
The mean is the average of the data set. Add all the numbers up then divide by the amount of numbers you had to start with.
The median of a set of data is the middlemost number. Order your set into least to greatest order then count inwards. If you have an even set or number then add both middle numbers and divide by 2.
The range of a set of data is the difference between the highest and lowest values in the set. Find your lowest and highest value numbers and subtract the lowest number form the highest one.

If the dimensions of a cylinder are doubled, then its volume is quadrupled.
True
False
Answers
Answer:
The answer is False.
If the dimensions of a cylinder are doubled, then its volume is quadrupled. The statement is false.
What is the volume of a right circular cylinder?Suppose that the radius of the considered right circular cylinder be 'r' units.
And let its height be 'h' units.
Then, its volume is given as:
[tex]V = \pi r^2 h \: \rm unit^3[/tex]
The right circular cylinder is the cylinder in which the line joining center of the top circle of the cylinder to the center of the base circle of the cylinder is perpendicular to the surface of its base, and to the top.
If the dimensions of a cylinder are doubled, the radius will become 2r, and the height will become 2h.
Hence, the new volume is:
[tex]V = \pi r^2 h \: \rm unit^3\\\\V = \pi (2r)^2 (2h)\: \rm unit^3\\\\V = 8\pi r^2 h \: \rm unit^3[/tex]
So, compared to the old volume, the new volume is increased eight-fold.
Therefore, the statement is false.
