Use one megabyte is approximately 106 bytes. one gigabyte is approximately 109 bytes. how many megabytes are in one gigabyte?

For this case we have to:

1 megabyte is defined asbytes

1 gigabyte is defined as bytes

We want to know how many megabytes there are in a gigabyte. For this we divide:

By power properties we have:

So we have that in a gigabyte there is one megabyte plus one kilobyte.

Checking:

1 megabyte

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
