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.

kicyunya [14]

Answer:

Case 1: a = 1.5, b = 2, c = -3

D = 22

Case 2: a = 2.3, b = -4, c = 1

D = 6.8

Case 3: a = 3.7, b = 9, c = -4

D = 140.2

Case 4: a = 4.6, b = -8, c = 5

D = -28

Case 5: a = 5.5, b = 7, c = -3

D = 115

Case 6: a = 6.9, b = -5, c = 2

D = -30.2

Case 7: a = 7.2, b = 6, c = -4

D = 151.2

Case 8: a = 8.3, b = -3, c = 4

D = -123.8

Case 9: a = 9.9, b = 4, c = -7

D = 293.2

Case 10: a = 10.4, b = 8, c = -5

D = 272

Step-by-step explanation:

For all second order polynomial, the discriminant is equal to:

D = b^{2}-4\cdot a \cdot c

Case 1: a = 1.5, b = 2, c = -3

D = 22

Case 2: a = 2.3, b = -4, c = 1

D = 6.8

Case 3: a = 3.7, b = 9, c = -4

D = 140.2

Case 4: a = 4.6, b = -8, c = 5

D = -28

Case 5: a = 5.5, b = 7, c = -3

D = 115

Case 6: a = 6.9, b = -5, c = 2

D = -30.2

Case 7: a = 7.2, b = 6, c = -4

D = 151.2

Case 8: a = 8.3, b = -3, c = 4

D = -123.8

Case 9: a = 9.9, b = 4, c = -7

D = 293.2

Case 10: a = 10.4, b = 8, c = -5

D = 272
