Answer:
96
Step-by-step explanation:
Out of every 11 students 7 were girls. Set up the following proportion.

11x = 7*77
x = 7*77/11
x = 49
49 of the student council members were girls.
Answer:
1865.16 m^2
Step-by-step explanation:
first let 's find radius of a circle
radius=diameter/2
=18/2
=9 m
area of a cylinder=2πrh+2πr2
=2*3.14*9*24 + 2*3.14*(9)^2
=1356.48 + 2*3.14*81
=1356.48 + 508.68
=1865.16 m^2
2/3 is exactly the same as 8/12
45-15= 30-28= 2+18=20
Is that what the question was asking??
