The height of a can of coke is in 11 cm and the radius is 6 cm calculate the total surface area of the can in cm^3 assuming that
Alecsey [184]

The total surface area of the can of coke is 641.143 cm².

<h3>What is the total surface area of the can?</h3>

A can of coke has the shape of a cylinder. A cylinder is a three-dimensional object that is made up of a prism and two circular bases. The total surface area of a closed cylinder can be determined by adding the area of all its faces.

Total surface area of the closed cylinder = 2πr(r + h)

Where:

  • r = radius = 6cm
  • h = height = 11 cm
  • r = pi = 22 / 7

Total surface area of the closed cylinder = (2 x 22/7 x 6) x (6 + 11)

(264 / 7) x (17)

37.714 x 17 = 641.143 cm²

Given 2 points (-2,6) and (5,-8) what is the slope, distance, and midpoint
Anastasy [175]
(-2,6) (5,-8)

slope = (y2 - y1) / (x2 - x1)
slope = (-8 - 6) / (5 - (-2) = -14/7 = -2 <==

midpoint = (x1 + x2)/2 , (y1 + y2)/2
m = (-2 + 5)/2 , (6 - 8)/2
m = (3/2, -1) <===

distance = sqrt ((x2 - x1)^2 + (y2 - y1)^2)
d = sqrt ((5 - (-2)^2 + (-8 - 6)^2)
d = sqrt ((5 + 2)^2 + (-14^2))
d = sqrt (7^2 + 14^2)
d = sqrt (49 + 196)
d = sqrt 245
d = 15.65 <==

find a positive angle less than one revolution around the unit circle that is co-terminal with the given angle -15pi/17
natta225 [31]
ANSWER
=\frac{19}{17} \pi

EXPLANATION

To find a positive angle that is coterminal with
-  \frac{15}{17}  \pi

We add multiples of 2π until we get a positive angle that is less than one revolution,


We add to obtain,


-  \frac{15}{17}  \pi + 2\pi


This simplifies to,

=  \frac{19}{17} \pi

This is the first positive angle that is coterminal with
-  \frac{15}{17}  \pi


and is less than one revolution.

Triangle ABC is an equilateral triangle.Find the angle of rotation that maps A to B
svet-max [94.6K]

The sum of the inner angles of any triangle is always 180°, i.e. you have


\alpha + \beta + \gamma = 180


In the particular case of an equilater triangle, all three angles are the same, so

\alpha = \beta = \gamma


and the expression becomes


\alpha + \beta + \gamma = \alpha + \alpha + \alpha = 3\alpha = 180


which implies \alpha = 60


So, if you rotate the triangle with respect to its center by 60 degrees, the triangle will map into itself. In particular, if you want point A to be mapped into point B, you have to perform a counter clockwise rotation of 60 degrees with respect to the center of the triangle.


Of course, this is equivalent to a clockwise rotation of 120 degrees.


Finally, both solutions admit periodicity: a rotation of 60+k360 degrees has the same effect of a rotation of 60 degrees, and the same goes for the 120 one (actually, this is obvisly true for any rotation!)
