3k=9+21
3k=30
k=10
Answer:
309.6 inches³
Step-by-step explanation:
To calculate the volume of the cylinder, we use the formula V = π^rh (where π = 3.14, r (which is an exponent) is the radius of the circle face of the cylinder, and h is the height of the cylinder). In this case, the radius is 3 inches, and the height is 10 inches. Therefore the equation is 3.14^3 = 30.96 * 10 = 309.6.
Therefore the can's volume is approximately 309.6 inches³.
