.
2 answers:
Find the area of the top, which is a circle.
Area of a circle = pi x r^2
Area = 3.14 x 1.5^2 = 7.065
Now for the volume multiply the area of the top by the height:
7.065 x 12 = 84.78 cubic inches
Round to the nearest tenth: 84.8 cubic inches
Answer:
Volume of cylinder is 84.78 inches.
Step-by-step explanation:
Volume of cylinder = π × r ² × h
Where,
- r , is the Radius of cylinder.
- h ,is the height of cylinder.
And we have given that
- Height of cylinder , h = 12 inches
- Radius of the height , r = 1.5 inches
- Value of π = 3.14
Substitute the values
Volume of cylinder = 3.14 × (1.5 inches) × 12 inches
= 3.14 × 2.25 inches² × 12 inches
multiply the values , we get
Volume of cylinder = 84.78 inches³.
84.8 inches³ is the round nearest to tenth.

Answer:
1 solution (x = 1.5)
Step-by-step explanation:
2x + 2 - 3x = 3x - 4
First, combine like terms
2 - x = 3x - 4
Add 4 to both sides
6 - x = 3x
Add x to both sides
6 = 4x
Divide both sides by 4
1.5 = x
