Students are getting signatures for a petition to increase sports activities at the community center. The number of signatures they get each day is 3 times as many as the day before. The expression 3^6 represents the number of signatures they got on the sixth day. How many signatures did they get on the first day?

The students got 3 signatures on first day.

Step-by-step explanation:

We are given the following in the question:

The number of signatures students get each day is 3 times as many as the day before.

Thus, the number of signatures form a geometric progression with common ratio 3.

Number of signatures on sixth day =

term in a geometric progression is given by:

where a is the first term of the series and r is the common ratio.

Thus, the first term of geometric progression is 3.

Thus, the students got 3 signatures on first day.

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 !

pretty sure 750 each month!
