At Central Middle School there are 525 students and 189 of them are in 6th grade. What percentage of the students are in 6th grade?

36%

Step-by-step explanation:

We basically multiply the smaller number (189) by the bigger number (525) and we get our result (0.36) (which we multiply by 100 to make it easily readable)

hi there!

how can i assist you?

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 !
