Answer:
A≈7563.59
Step-by-step explanation:
Using the formulas
A=πrl+πr2
l=r2+h2
Solving forA
A=πr(r+h2+r2)=π·27·(27+562+272)≈7563.59277
Find the volume of the cylinder. Round your answer to the nearest hundredth of a cubic meter.
Answer:
I think that the answer may be volume = 169.65
Step-by-step explanation:
The volume of cylinder whose radius 3m and height 6m is 169.56 cm³ ≈ 170 cm³
What is Volume of Cylinder?The volume of a cylinder is the density of the cylinder which signifies the amount of material it can carry or how much amount of any material can be immersed in it. Cylinder’s volume is given by the formula, π[tex]r^2h[/tex], where r is the radius of the circular base and h is the height of the cylinder.
Here, Radius of Cylinder = 3 m.
Height of Cylinder = 6 m.
Volume of Cylinder = πr²h
= 3.14 X 3 X 3 X 6
= 169.56 cm³
≈ 170 cm³
Thus, the volume of cylinder whose radius 3m and height 6m is 169.56 cm³ ≈ 170 cm³.

A 60 hours
CB 75 hours
C 120 hours
D 160 hours
What is the total of the surface are of this figure
Answer:
answer: 200
Step-by-step explanation:
Finding surface area for triangles is base × height ÷ 2 So 10 x 10 = 100 100 ÷ 2 = 50 sense all of these triangles are identical we just have to multiply 50 with the number of triangles so
50 × 4 = 200 So 200 is our answer. Hope this helps!

How can a sequence of transformations be used to justify whether two figures are congruent or similar?
Answer:
A sequence of transformation can move two congruent figures to the same place (vertical / horizontal shifts). This causes them to perfectly overlap, proving their congruency.
A sequence of transformations can be used to show that something is similar, because if one were to transform a figure with only shrinks / stretches, one can shrink / stretch them to make them congruent. If only shrinks or stretches were done, and if the result of the transformation is congruent to the other figure, then the figures are similar (sides are proportional and shrinking/stretching them proves proportionality to other figure).

How do you write an equation of a line that passes through (4,3) and has a slope of 2?
Answer:
y = 2x - 5
Step-by-step explanation:
y-intercept form is y = mx + b, where m is the slope and b is the y-intercept. We know the slope is 2, so all that's left is to find the y-intercept. To do this, for every 1 we subtract from x in (4,3), we take away 2 from y because the slope is two. We keep doing this until x is zero. The remaining y-value is the y-intercept.
Answer:
[tex]y = 2x-5[/tex], see below.
Step-by-step explanation:
There is enough information to make a point slope equation that we can later convert into slope intercept.
Point slope form is:
[tex]y-y_1=m(x-x_1)[/tex]
[tex](x_1,y_1): \text{A point.} \\\\m - \text{Slope.}[/tex]
We are given the slope of 2 and the point (4,3).
Replace the variables with the given information.
[tex]y-y_1=m(x-x_1)\rightarrow y-3=2(x-4)[/tex]
With the equation we will now convert it into slope intercept form:
[tex]y-3=2(x-4)\\\\y-3=2x-8\\\\y-3+3=2x-8+3\\\\\boxed{y=2x-5}[/tex]

There are 750 people at a football game Out of this number 320 are students what percent of people at the football game are not students? Round to the nearest hundredth,if needed.
The percent of people at the football game are not students will be 57.33%.
What is mean by Percentage?
A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
Given that;
The number of peoples in football game = 750
The number of students = 320
Now.
Find the percent of people at the football game are not students as;
Number of people are not students = 750 - 320
= 430
Thus, The percent of people at the football game are not students is;
Percent = 430 / 750 x 100
= 0.5733 x 100
= 57.33%
Hence, The percent of people at the football game are not students will be 57.33%.

Karinna's aquarium, which is in the shape of a rectangular prism, can hold 80,000 cubic centimeters. The base measures 100 cm by 40 cm. What is the height of the aquarium in centimeters?
Answer:
20 centimeters
Step-by-step explanation:
Karina's aquarium can hold 80 liters,which is equal to 80,000cm³.The base measure 100cm by 40cm.What is the height of the aquarium in centimeters?Round your answer to the nearest hundredth.
The shape of an Aquarium = Rectangular Prism
Volume of the rectangular prism = L × Width × Height
Volume = 80 Liters = 80,000 cm³
Base = 100 cm × 40 cm
Height of the aquarium is calculated as:
80,000cm³ = 100 cm × 40 cm × h
h = 80,000cm³/100 cm × 40 cm ×
h = 20 cm
The height of the aquarium = 20cm

Step-by-step explanation:
2x - 1/4 + x/3 = 2
2x + x/3 = 2 1/4 (added 1/4 to both sides)
6x = 6.75 (multiplied both sides by 3)

The makers of a certain diet cola claim that its taste is identical to the full-calorie version. To test this claim, a
researcher recruits 175 volunteers, has them drink samples of both colas from identical cups in a randomized order,
and then asks them to identify which sample is the diet cola. If we assume that the volunteers truly cannot tell the
difference, then the probability that they correctly identify the diet cola is 0.5.
X = the number of volunteers who correctly identify the diet cola and is a binomial random variable.
Calculate the mean and standard deviation of X. Round to 4 decimal places, when necessary.
