Find the volume of a right circular cone that has a height of 12.1 m and a base with a circumference of 17.7 m. round your answer to the nearest tenth of a cubic meter.

The volume of a right circular cone is

.

If a circumference of a base circle is 17.7 m, then using formula for circumference of a circle, you can find the radius:

.

Then the volume is:

.

Step-by-step explanation:

The volume of a cone is defined as:

So, a cone has a circular base, and its area is:

Replacing this relation in the volume equation:

Now, the problem gives us the height but no the radius, instead it gives the circumference length, which we can use to find the radius:

Then, we use this radius to find the volume:

Using :

Therefore, the volume is

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
