Three students are sitting in the first row. in the second row, three students sit behind each of those students, and so on. how many students are sitting in the fifth row?

sorry i just don’t get it

243 students

Step-by-step explanation:

First row: 3 students

Second row: 9 students (3^2)

Third row: 27 students (3^3)

Fourth row: 81 students (3^4)

Fifth row: 243 students (3^5)

The basic logic behind this question is that each row is a "cube" --> the fifth row is 3 ^5, meaning 3 x 3 x 3 x 3 x 3 (equals 243!!)

Knowing this, you could even solve for how many kids are in, say, the 12th row. It would just be 3^12.

just find the gcf and solve the gcf's until you get each answer i have a really good feeling somethings missing xd (like the dimensions of the fence) *cough *cough *hint *hint

step-by-step explanation:

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
