<h2>
Answer:</h2>
The surface area of a shape is the sum of the area of all of its faces. To find the area of a cylinder, you need to find the area of its bases and add that to the area of its outer wall. The formula for finding the area of a cylinder is A = 2πr2 + 2πrh.
<h2>
Step-by-step explanation:</h2>
- Surface area of a cylinder = 2πr 2 + 2πrh
- Volume of a cylinder = πr 2 h
- You need to know the radius and height to figure both the volume and surface area of a cylinder.
- Answers for volume problems should always be in cubic units.
- Answers for surface area problems should always be in square units.
Answer:
x=-20
Step-by-step explanation:
3/4x-4=-19
3/4x=-19+4
3/4x=-15
x=-15/(3/4)
x=(-15/1)(4/3)
x=-60/3
x=-20
If you want an aquarium in shape of a cube with volume of 8000, then use the formula for volume of cube to find the length of one side:
V = s^3
where
s = side length
Substitute,
8000 = s^3
s = cuberoot(8000)
s = 20 inches
Well, if you have to draw this on a graphing paper, you should first make a scale to fit the drawing, like 1 inch = 0.5 cm, so a side length of 20 inches is equivalent to 10 cm on your graphing paper.
Hope this helped!
Answer:
[12/(4c)] + [12/(6c)] = 2.5
Step-by-step explanation:
time = distance/speed
You know the speeds upstream (5-1)c and downstream (5+1)c, the distance, and the total time for both trips. This information can be combined to give the equation above.
_____
The first equation assumes the trips upstream and down took 2.5 hours each.
The second equation is an incorrect combination of the numbers, as the units on the left are miles²/hour and are equated to hours on the right.
The third equation makes appropriate use of the relation between speed, distance, and time.
Answer:
<u>AB and GH</u>
Step-by-step explanation:
<u>Calculation of slope of each segment</u>
- AB = -1/4
- CD = -5/6
- EF = -5/5 = -1
- GH = -2/8 = -1/4
Parallel lines have the same slope.
⇒ <u>AB and GH</u> are the pair of segments which are parallel
