Answer:
13
Step-by-step explanation:
20÷1.5 since there is not X
Another way to express 7/10 is .7
So, 4 times .7 equals 2.8.
Step-by-step explanation:
(3x-11)+(2x+11)+2y = 180
5x+2y = 180
(3x-11)+(2x+11)=2y
5x = 2y
x = 18
y = 45
ANSWER
The area of the base is 14.5π in²
EXPLANATION
The volume of a cylinder is given by

Or
V=Bh
It was given that the volume of the cylinder is 174π in³.
The height was given as 12 inches.
We substitute to get,
174π=12B
Divide both sides by 12 to get:
B=14.5π in²
Hence the area of the base is 14.5π in²
