since the length and width are the same, it is actually a square
area of a square is S^2
sqrt(128) = 11.3137
round off as needed
Answer: The median is 13.5 and the mean is 13.3
Step-by-step explanation:
The median is the middle number when you arrange the data in ascending order. The mean is all the data added up and divided by the number of data points, which is 8. The mean was 13.25, but rounded to the nearest 10th is 13.3.
Answer:
Step-by-step explanation:
(10 - 8)/(-21 + 9)= 12/-12= -1
y - 8 = -1(x + 9)
y - 8 = -x - 9
y = -x - 1
Answer:
376.991 cm²
Step-by-step explanation:

Surface Area = 2π(5²) + 2π(5)(7)
= 50π + 70π
= 120π
= 376.9911184... ≈ 376.991
<h2>Derive Surface Area of A Cylinder</h2>
If you take a look at a net of a cylinder, you can see it is composed of two circles(bases) and a rectangular strip with the length of the diameter of the circle
The formula for the area of a circle = πr², and since there are 2, it is 2πr²
The formula for circumference of a circle = 2πr, and since we are multiplying that by the height by the height of the cylinder, it is 2πrh
∴ 2πr² + 2πrh
