Answer:
263.76
Step-by-step explanation:
To answer this question, we need to know the equation for surface area of a cylinder which can be given as Surface Area=2*pi*
+2*pi*R*H, where R is the radius of the cylinder (also can be calculated as Diameter/2=6/2=3) and H is the height of the cylinder which is given as 11. Considering pi=3.14, the surface area of the cylinder can now be calculated as 2*3.14*
+2*3.14*3*11=263.76.
Answer:
The error is located in step 9, because the student made the following operation: 
, instead of 
, presented in step 4) of our demonstration. The real solution is 9.
Step-by-step explanation:
First, we proceed to show the appropriate process to solve the equation for 
by algebraic means. That is:
1) 
Given
2) ![(-4)\cdot [6+(-r)] = 12](https://tex.z-dn.net/?f=%28-4%29%5Ccdot%20%5B6%2B%28-r%29%5D%20%3D%2012)
Definition of substraction
3) 
Distributive property
4) 
/
5) ![4\cdot r +[24+(-24)] = 12 +24](https://tex.z-dn.net/?f=4%5Ccdot%20r%20%2B%5B24%2B%28-24%29%5D%20%3D%2012%20%2B24)
Compatibility with addition/Commutative and associative properties
6) 
Existence of additive inverse/Modulative property
7) 
Compatibility with multiplication/Commutative and associative properties
8) 
Existence of multiplicative inverse/Definition of division/Result
The error is located in step 9, because the student made the following operation: , instead of , presented in step 4) of our demonstration. The real solution is 9.
