Find the ninth term of the geometric sequence a4= -135,r=-3

The nth term of the geometric sequence is is 32805

Step-by-step explanation:

The nth term of a geometric sequence is given by

Where is the first term and is the common ratio

We are given the fourth term of this sequence

The common ratio is

Once we find the 1st term then we can find any other term.

So the ninth term of this geometric sequence is

Therefore, the nth term of the geometric sequence is is 32805

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

sorry

sorry, but im pretty sure its a now that i look at it
