Answer: D) 602.88

Step-by-step explanation:

A cylinder is basically a circle prism.  Any prism volume can be found by taking the area of the base * the height.  The circle area is 4^2*3.14 = 50.24.  Then multiply that by the height(12)  50.24*12 = 602.88

Also, so far all of your questions that I've answered have been D...

Answer:

0.6 inch

Step-by-step explanation:

The volume of a sphere is calculated through the equation,

                           V = 4πr³/3

Which means that the radius is calculated by the equation,

                                (3V/4π)^(1/3) = r

Substituting,

           Sphere A,       (3x30/4π)^(1/3) = r = 1.927 in

           Sphere B,        (3x10/4π)^(1/3) = r = 1.336 in

When we subtract the radius, we get an answer of 0.59 inch. Therefore, the answer to this item is approximately 0.6 inch.

In triangle ABC, the size of the B is 4 times the size of angle A, and the size of angle C is 14 cel less than 5 times the size
Neporo4naja [7]

Answer:

A = 19.4

B = 77.6

C =83

Step-by-step explanation:

Given

By interpreting each line, we have:

B = 4A

C = 5A -14

Required

Solve for A, B and C

In a triangle,

A + B + C = 180

Substitute expressions for B and C

A + 4A + 5A - 14 = 180

A + 4A + 5A  = 180+14

10A  = 194

Solve for A

A = 194/10

A = 19.4

B = 4A

B = 4 * 19.4

B = 77.6

C = 5A -14

C =5 * 19.4 - 14

C =83
