The answer to the question is a
Answer:
x=7
Step-by-step explanation:
(2x-2)=(x+5)
2x-2=x+5
(2x-x)-2=5
x-2=5
x=(5+2)
x=7
From the information given we know that the height of the cylinder is 3 in, and the volume of the cylinder is 10 in. cubed (assuming that the glass was full). We can substitute these values in the formula for volume.
Volume for Cylinder = Bh
10=pi x radius squared x 3
10/3 = 22/7 x radius squared
(10/3) x (7/22) = radiux squared
(5/3) x (7/11) = radius squared
35/33 = radius squared
![35 \sqrt{33}/33](https://tex.z-dn.net/?f=35%20%5Csqrt%7B33%7D%2F33%20)
= radius
