Step-by-step explanation:
The teachers will not be doing the activity, so their opinion is irrelevant. All boys in each grade targets a some audience and leaves the girl's voices unheard. All the students in the social studies club only represent a small portion of students who take the class. A poll of all the students in each grade will give the teacher the results they desire.

3.14 x 8squared x 30 = 6028.8
Answer = B
Answer:
Step-by-step explanation:
the vale of x differs in each situation are we talking AB value
P of triangle = a + b = c = 90
<span>ratio 3:4:5
so a = 3x, b = 4x , c = 5x
3x + 4x + 5x = 90
12x = 90
x = 90/12 = 7.5
a = 3x = 3 * 7.5 = 22.5
b = 4x = 4 * 7.5 = 30
c = 5x = 5 * 7.5 = 37.5
Answer:
1st side = 22.5
2nd side = 30
3rd side = 37.5
Double check: 22.5 + 30 + 37.5 = 90 (perimeter)</span>
