Circumference = 31.4
Surface area:
Substitute the values of the radius (r=5), the height (h=9), and an approximation for π(3.14) into the formula.
SA=2(3.14)(5)^2+2(3.14)(5)(9)
Simplify each term.
SA=157+282.6
Add 157 and 282.6 to get 439.6.
Surface area=439.6cm^2
Volume:
Substitute the values of the radius (r=5), the height (h=9), and an approximation of Pi (3.14) into the formula to find the volume of the cylinder.

Answer:
The total capacity of the tank = 16 gallons
32 bottles can be filled with the water in the tank.
Step-by-step explanation:
Let the total capacity of the tank = K gallons
Now here, according to the question
3/4 capacity of the tank = 12 gallons
⇒
or, K = 16 Gallons
So, the total capacity of the tank is 16 gallons.
Now, capacity of 1 bottle = 0.5 gallon= (1/2) gallon
So, number of bottles filled = Capacity of each bottle x Total capacity of tank
n = 0.5 gallon x 16 gallons = 32 bottles
Hence, 32 bottles can be filled with the water in the tank.
What comes after
Answers
If you look at it the pattern is:
Multiply by 4, then divide by 2
4 times 4= 16
16 divided by 2= 8
8 times 4= 32
32 divided by 2= 16
Now you would multiply by 4
16 times 4= 64
multiply by 4, divide by 2, multiply by 4...etc
so what comes next is 16*4=64

The dimensions of length can be measured using a ruler, and the angle measurement can be made with the use of a protractor
The dimensions (calculated) of the figure are:
Angles formed at each intersection;
Angle A is approximately 97.125°
Angle B is approximately 53.6°
Angle C is approximately 26.6°
Lengths of the straight sides;
Side AB is approximately 3.6
Side BC is 8
Side AC is approximately 6.7
Please find attached the screen grab of the image
The reason the above values are correct is as follows:
Question: The coordinates of the points A, B, and C, obtained from a similar question online are; A(3, 4), B(1, 1), and C(9, 1)
Please find attached the diagram of the tree paths that intersect at the points A, B, and C
The required parameter:
To measure and record the angle formed at each intersection
The angles can be measured using a protractor, however, by calculation, we have;
The length of AB = √((3 - 1)² + (4 - 1)²) = √13 ≈ 3.6
The length of BC = √((9 - 1)² + (1 - 1)²) = 8
The length of AC = √((9 - 3)² + (1 - 4)²) = √45 = 3·√5 ≈ 6.7
By cosine rule, we have;
Therefore, the angles formed at each intersection are;
Angle A ≈ 97.125°
Angle B ≈ 53.6°
Angle C ≈ 26.6°
The lengths of the straight side are;
Side AB ≈ 3.6
Side BC = 8
Side AC ≈ 6.7
