The average number of people at a concert over 3 nights is 125. on the first night, there were 151 people at the concert. the same number of people attended the second and third night. how many people attended on each of the second and third nights?

164 people

Step-by-step explanation:

Let's say x = # of people in night 2 and 3

Average = (n₁ + n₂ + n₃ + ...)/n

Plug in known numbers: (125 + x + x)/3 = 151

Multiply + simplify: 125 + 2x = 453

Subtract: 2x = 328

Divide: x = 164

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 !
