Answer:

3054

Step-by-step explanation:

The formula for cylinder volume is

V1 = π * r^2 *h

while formula for sphere volume is  

V2= 4/3 *  π  * r^3

Since the height of the cylinder is 12, we can substitute h the equation into

V1 = π * r^2 *12

The volume and radius of the cylinder are the same as the sphere, so we can combine both equations to find r.  

V1= V2

π * r^2 *12 =  4/3 *  π  * r^3  

12 = 4/3 * r

r= 12*3/4

r=9

After we find the radius, we can find the sphere volume

V2= 4/3 *  π  * r^3  

V2= 4/3 *  π  * 9^3  

V2=  3053.62 = 3054

olya-2409 [2.1K]

Answer:

2,850

Step-by-step explanation:

4.25 x 9 = 38.25

4.25 x 13 = 55.25

4.25 x 12 = 51

13.70 x 92 = 1260.4

3.28 x 130 = 426.4

8.06 x 126 = 1015.56

all totals would equal 2,846.86, which to the nearest would be $2,850

E-1, e-2 and e-3 are three engineering students writing their assignments at night. Each of them starts at a different time and
Bas_tet [7]

E-3 will be the first student to start writing the assignment.

It is clearly stated in the statement that the order of starting the assignment and the order of the completion of the assignment is not the same, the digit in the name of the executive is also not same. This information puts some restrictions.

E-1 can neither be the first one to start nor the first one to complete. Similarly, E-2 cannot be the second one and E-3 cannot be the third one.

It is given that the last student (the third one) to start is the first student (the first one) to complete. This can neither be E-3 nor E-1. It is E-2

The final arrangement is as follows.

                                 Start           Complete

First                           E-3              E-2

Second                      E-1               E-3

Third                          E-2              E-1

E-3 is the first one to start writing the assignment.

What is the total after a 10% discount of 346.10
AVprozaik [17]
It is 311.49. You would multiply 0.10 and 349.10, which is 34.61. Then subtract 34.61 from 349.10, which is 311.49. So, after a 10% discount of 346.10, the answer would be 311.49
