Answer:
87.9 in³ OR 88.0 in³
Step-by-step explanation:
Concepts
The volume of a cylinder is [tex]\pi r^2h[/tex], where r = radius and h = height.
The radius is twice the diameter.
Application
We are given the diameter as 4 inches, so the radius is 2 inches. The height of the cylinder is 7 inches. Now, we just apply our aforementioned formula and plug in its values of r and h. Since I don't know if you're using pi as 3.14 or just using the exact value of pi, I have provided two different answers at the top.
Solution
1:
- [tex]3.14*2^2*7[/tex]
- [tex]3.14*4*7[/tex]
- [tex]3.14*28[/tex]
- [tex]87.92[/tex]
- [tex]87.9[/tex]
2:
- [tex]\pi *2^2*7[/tex]
- [tex]\pi *4*7[/tex]
- [tex]28\pi[/tex]
- [tex]87.9645943005...[/tex]
- [tex]88.0[/tex]
