For this case we have that by definition, the volume of a cylinder is given by:

V = \pi * r ^ 2 * h

Where:

V: It's the volume

A: It is the radius of the cylinder

h: It is the height of the cylinder

We have to:

V = \pi * (7.2) ^ 2 * 12\\V = \pi * 51.84 * 12\\V = 1954.32195794513 \ m ^ 3

On the other hand, the volume of the cone is given by:

V = \frac {\pi * r ^ 2 * h} {3}

V: It's the volume

A: It is the cone radius

h: It is the height of the cone

We have:

V = \frac {\pi * (7.2) ^ 2 * 11} {3}\\V = \frac {\pi * 51.84 * 11} {3}\\V = 597.153931594347 \ m ^ 3

Thus, the total volume is given by:

V = 2551.47588954 \ m ^ 3

If we round up we have:

V = 2551.48 \ m ^ 3

Answer:

V = 2551.48 \ m ^ 3

Identify what Number property is shown for each statement
Evgen [1.6K]

1. Commutative property of multiplication = G. 10x3=3x10

3. Associative property of Addition = K. (6+2) + 1 = 6 + (2 + 1)

4. Associative property of multiplication = F. (5x3)x4=5x(3x4)

5. Symmetric property = J. If 11 = y then y = 11

6. Reflexive property = A. 21=21

7. Transitive property = B. If k=15 and 5 = 3m. Then k = 3m

8. Zero property of multiplication = D. 9x0=0

9. multiplicative inverse = I. 8x1/2=1

10. Zero property of multiplication = L. 2+(2-)=0

11. Additive identity = E. 4+0=4

12. Multiplicative identity = H. 19x1=19

Hope this helps!
