The radius is 3 inches and the height is 2 inches. Then the correct option is C.
<h3>What is the volume of a right circular cylinder?</h3>
Let r be the radius and h be the height of the cylinder.
Then the volume of the cylinder will be
V = π r²h cubic units
The volume of the cylinder is given as
V = 18π cubic inches
Then factor of 18 will be
18 = 2 x 3 x 3
18 = 2 x 3²
Then we have
V = π x 3² x 2
Then the radius is 3 inches and the height is 2 inches.
Then the correct option is C.
More about the volume of the cylinder link is given below.

Answer:
1. perimeter of Trapezoid = 35x+18
Option F is correct.
2. perimeter of square = 16x-32
Option C is correct.
3. perimeter of Pentagon = 10x-20
Option A is correct.
4. perimeter of Rhombus = 28x+8
Option H is correct.
Step-by-step explanation:
1. Trapezoid Perimeter
Side1 a: 9x+4
Side2 b: 7x+8
Side3 c: 12x-2
Side4 d: 7x+8
The formula used is:
Putting values and finding perimeter
So, perimeter = 35x+18
Option F is correct.
2. Square Perimeter
Side of square = 4x-8
The formula used is:
where a is side of square
Putting values in formula
So, perimeter of square = 16x-32
Option C is correct.
3. Pentagons perimeter
Side of pentagon= 2x-4
The formula used is:
where a is side of pentagon.
Putting values in formula
So, perimeter of Pentagon = 10x-20
Option A is correct.
4. Rhombus perimeter
Side of Rhombus=7x+2
The formula used is:
where a is side of rhombus
Putting values in formula
So, perimeter of Rhombus = 28x+8
Option H is correct.
Answer:
b and e.
Step-by-step explanation:
You will find this by solving each equation for 15b (get 15b by itself)
Answer: 15
Step-by-step explanation: All the information you need is a=3
5a is the same as saying 5xa or 5x3, so there you have it- 15
Hope this helps <3
