Step-by-step explanation:
Step-by-step explanation:
-4(3m-10)-6(-7m-6) = -74
-12m + 40 + 42m + 36 = -74
30m + 76 = -74
30m = - 150
m = - 5
Answer:
I am pretty sure its 45 degrees
Step-by-step explanation:
The right answer is Option C.
Step-by-step explanation:
Given,
Diameter = 6 cm
Radius = 
Height = 8 cm
π = 
Surface area = 2πrh+2πr²
Surface area = 
Surface area = 
Surface area = 
Surface area = 207.4 cm²
Rounding off to nearest whole number
Surface area = 207 cm²
The surface area of cylinder is 207cm².
The right answer is Option C.
