The answer is:
20 m² .__________________________________________________________Explanation:__________________________________________________________
Formula for "S.A." (Surface area) of a cylinder
S.A.
= 2
r² + 2
* r * h ;
_______________________________________in which "r" = length of radius of circle at the end; and "h" = "height" ;
__________________________________________Given: r = 2 m ; and h = 3 m ;
__________________________________________ We can "plug in" these given values; and solve for the "surface area" in terms of
"
" .
____________________________________________S.A. = 2
r² + 2
* r * h ;
= 2
* (2)² + 2
* (2) * (3) ;
= 2
* (4) + 2
* (6) ;
= (8
) + (12)
= 20 m² ._______________________________________
Answer:
x = 4.17
Step-by-step explanation:
We can use a ratio to solve
4.2 k 2 k
---------------- = ---------------
8.76 x
Using cross products
4.2 * x = 2 * 8.76
4.2x =17.52
Divide by 4.2
x=4.17
Translation will reduce x coordinate by 2: (0,4), (5,6) and (3,2)
Rotation 90 CCW will change (x,y) to (-y,x): (-4,0),(-6,5),(-2,3)
