Answer:
Step-by-step explanation:
−6x+6−7=2x+8
-1-8=2x+6x
8x=-9
x= -
Step-by-step explanation:
0.5 ( r + 2.75 ) = 3
r + 2.75 = 3 / 0.5
r + 2.75 = 6
r = 6 - 2.75
r = 3.25
Step-by-step explanation:
Since the options are not clear enough, please kindly see the attached file for more explanation
Area of cylinder = 2 pi r h + 2 pi r^2
= 2 * 3.14 * 4 * 12 + 2 * 3.14 * 4^2
= 301.44 + 100.48
Area of cylinder = 401.92 cm^2
