A triangular prism. The rectangular sides are 2 centimeters by 13 centimeters, 12 centimeters by 2 centimeters, and 5 centimeters by 2 centimeters. The 2 triangular sides have a base of 5 centimeters and height of 12 centimeters. Which equation could be used to find the surface area of the net of the triangular prism shown? SA = (1/2)(5)(12) + (5)(2) + (12)(2) + (13)(2) SA = (1/2) (5)(13) + (1/2) (5)(13) + (5)(2) + (13)(2) + (12)(2) SA = (1/2)(5)(12) + (1/2)(5)(12) + (5)(2) + (12)(2) + (13)(2) SA = (2)(5)(13) + (5)(2) + (13)(2) + (12)(2)

What is the difference between mean and median
Answers
The difference between the mean and median is that the mean is the average number. f.e: 1, 2, 2, 2, 3, 3, 4, 5 - and if you add all those up, the mean would be 3, or 2.
But the median is the number in the middle Number.
What if you have 2 medians, though?
Well, that’s easy to solve IMO.
F.e: 22, 22, 23, 23, 23, 24, 24, 24, 25, 25
The median is either 23 or 24, right?
Okay. That’s simple. But what exactly do we do?
Let me show you:
So get the sum of 23 and 24, which is 47.
Now divide 47 by 2. And what do we get?
23.5.
Now round that, and you get 24. So 24 is the median!
Hope that helps!
Answer:
mean is the AVERAGE of all numbers
Step-by-step explanation:
because when you add up all the numbers then you divide it by the TOTAL NUMBER of NUMBERS!
and a median is the middle number in a sorted, ascending or descending, list of numbers and can be more descriptive of that data set than the average.
hope this helps

1. a round cake pan that is 2 inches deep and has a 7-inch diameter
2. a 6 inch × 9-inch rectangular cake pan that is 2 inches deep
Which of these pans has the larger volume? Justify your answer.
Note: Write an essay-like answer, and I will give brainliest and rating.
Answers
The answer is
round cake - 82.42 in²
rectangular cake - 114 in²
Round cake:
d = 7 in
r = d/2 = 7 in / 2 = 3.5 in
h = 2 in
The surface are of a cylinder is:
A = 2πr² + 2πrh
The surface are of the round cake (which is actually a cylindrical cake) excluding the bottom is:
A = 2πr² + 2πrh - πr²
A = πr² + 2πrh
A = 3.14 * 3.5² + 2 * 3.14 * 3.5 * 2
= 38.46 + 43.96
= 82.42 in²
Rectangular cake:
w = 6 in
l = 9 in
h = 2 in
The surface are of a rectangle is:
A = 2wl + 2wh + 2lh
The surface are of the rectangular cake excluding the bottom is:
A = 2wl + 2wh + 2lh - wl
A = wl + 2wh + 2lh
A = 6 * 9 + 2 * 6 * 2 + 2 * 9 * 2
= 54 + 24 + 36
= 114 in²

Answer:
Radius=10
Diameter=20
circumference=62.8
Area=314
Answer:
Radius: 10 inches
Diameter: 20 inches
Circumference: 62.8 inches
Area: 314 inches squared
Step-by-step explanation:
Radius:
They have already given you the radius (10), so no formula is needed.
Diameter:
To find the diameter, multiply the radius by 2, so:
2 × 10 = 20
Circumference:
To find the circumference, use this formula:
C=2πr
2 × π (3.14) = 6.28
6.28 * 10 = 62.8
Area:
To find the area, use this formula:
A=πr²
π (3.14) × 100 = 314
