Answer:
![-\frac{5}{2}](https://tex.z-dn.net/?f=-%5Cfrac%7B5%7D%7B2%7D)
Step-by-step explanation:
Step 1: Put this into an equation
![-\frac{5}{3} - x = \frac{5}{6}](https://tex.z-dn.net/?f=-%5Cfrac%7B5%7D%7B3%7D%20-%20x%20%3D%20%5Cfrac%7B5%7D%7B6%7D)
Step 2: Solve for x
![-x = \frac{5}{6} + \frac{5}{3}](https://tex.z-dn.net/?f=-x%20%3D%20%5Cfrac%7B5%7D%7B6%7D%20%2B%20%5Cfrac%7B5%7D%7B3%7D)
![-x = \frac{5}{2}](https://tex.z-dn.net/?f=-x%20%3D%20%5Cfrac%7B5%7D%7B2%7D)
![x =- \frac{5}{2}](https://tex.z-dn.net/?f=x%20%3D-%20%5Cfrac%7B5%7D%7B2%7D)
Therefore you need to subtract
from
to get ![\frac{5}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B6%7D)
Answer: 660 cm²
Step-by-step explanation:
Surface area of a cylinder = 2πr² ± 2πrh = 2πr ( r + h )
π = 22/7
r = 6 cm
h = 11.5 cm
Lateral surface area = 2 x 22/7 x 6 ( 6 + 11.5 )
= 660 cm²
