There are 250 students taking either band or chorus. If there are 180 students taking band and 60 students in both band and chor
Olegator [25]

Answer:

<em>There are </em><em>70</em><em> students only in chorus.</em>

Step-by-step explanation:

Total number of students is 250

Out of 250, 180 students took band.

And 60 took band and chorus, i.e this is the intersection of the 2 groups.

The Venn diagram is attached below.

So, the number of students who took only band = 180-60 = 120

Total number of students or sum of the 3 regions is 250.

So, the number of students who took only chorus = 250-180 = 70

The volume of a sphere is 972(pi)ft3.
pav-90 [236]

Here are some simple equations that can be a life saver with this stuff :

vol of a sphere =

v = \frac{3}{4} \pi \: {r}^{3}

Circumference =

2 \times \pi \times r

sorry this might not be very helpful. I haven't don't this since last year. You basically have to work backwards. so plug in 972 for V and then do (3/4)×3.14.

then take the answer u got for ^^ and divide it by 2? not sure.
