Volume of a cone=1/3 times height times area of base
area of base=area of circle=pi times r^2
r=3
aprox pi to 3.14
height=9
so we have
volume=1/3 times 9 times 3.14 times 3^2
3^2=9
1/3 times 9 times 3.14 times 9
3 times 3.14 time s9
9.42 times 9
84.78
nearest tenth
0.78=0.8
answer is 84.8 ft^3
The blue group did because they ate 7 slices out of 8 while the green team only ate 2 out of 8
-3m>26-5
-3m>21
m>21/(-3)
m<-7=>m∈(-∞, -7)
-3 is negative and dividing an inequality by something negative switches its sign, that's why I wrote < instead of >
Y=mx+b. I think because +b gives it away which never goes through the origin, and we just reviewed this at school.
