The formula for the circumference of a circle is C = 2pi*r, where r is the radius.  Here, 7850 units = C = 2pi*r.

Dividing 7850 units by 2pi, we get
        7850 units
r  = ----------------- = 1249 units (to the nearest unit)
           2pi

Find the volume of the solid obtained by rotating the region bounded by the given curves about the specified axis. y = 64x−8x^2,
Mandarinka [93]
We need to get the limits first. When y = 0
0 = 64x - 8x^2
x = 0 and x = 8
The volume is
V = ∫ y dx from 0 to 8
V = ∫ (64x - 8x^2) dx from 0 to 8
V = 32x^2 - 8x^3/3 from 0 to 8
V = 682.67<span />

a survey asked 72 randomly chosen students if they were going to attend the school play. twelve said yes. if there are 210 ticke
Ugo [173]
We can solve this by setting up a proportion:

12 seeing the play/ 72 students = 210 seeing the play/ x students

We can cross multiply to solve for x:

(12)x=(72)(210)
12x=15,120
x=1,260 students who attend the school
