How should I solve this to get the elapsed time
8090 [49]

Answer:

Subtract the hours to get 12-3 = 9

Or you could start at 3 PM, and count your way up one hour at a time, until you get to 12 AM. You should count out 9 hours in total.

An alternative is you could note from 3 PM to 3 AM is a span of 12 hours. Take 3 hours away from 3 AM, and you'll rewind the clock back to 12 AM. So 12-3 = 9. :-)

plz brainlist plz ;-)

The volume of a sphere whose diameter is 18 centimeters is how many cubic centiemters
Arturiano [62]

Answer:

3053.63 cm^3

Step-by-step explanation:

Volumme of a sphere =  \frac{4}{3}\pi*r^3.

We do not have the radius of the sphere, but we have its diameter.

We know that there is a relationship between radius and diameter.

d = 2r\\r = \frac{d}{2}

Then the formula of the volume of a sphere according to its diameter is:

\frac{4}{3}\pi (\frac{d}{2}) ^ 3\\\\\frac{4}{3}\pi(9)^3 = 972\pi = 3053.63 cm^3\\\\
