Answer:

3.064

Step-by-step explanation:

Given the data:

X = 15.5, 19, 21.1, 21.8, 28

The mean absolute deviation is calculated thus :

MAD = |x - mean| / n

Where n = sample size

Mean = Σx / n = 105.4 / 5

Mean = 21.08

MAD = (|15.5 - 21.08| + |19 - 21.08| + |21.1 - 21.08| + |21.8 - 21.08| + |28 - 21.08|) / 5

MAD = 3.064

Work our the surface area of this cylinder?

tankabanditka [31]

Answer:

$A=522.97\ \text{cm}^2$

Step-by-step explanation:

Given that,

The diameter of the cylinder, d = 8 cm

Radius, r = 4 cm

Height of the cylinder, h = 16.8 cm

We need to find the surface area of this cylinder. The formula for the surface area of the cylinder is given by :

$A=2\pi r^2+2\pi rh\\\\=2\pi r(r+h)\\\\=2\times \dfrac{22}{7}\times 4\times (4+16.8)\\\\=522.97\ \text{cm}^2$

So, the surface area of the cylinder is $522.97\ \text{cm}^2$
