First, find the number of females in the class. 
Then, just write the ratio. 
I plugged it in to a truncated square pyramid calculator and got v=76
the formula for this shape is V=1/3(A squared+AB+B squared)H.
The correct answer to question 1 is: (C. P (v)=4500v
The correct answer to question 2 is: (A. 12
Hope i helped!:)
Answer:
8 cm
Step-by-step explanation:
volume of a cylinder is v=pi x r^2 x h
substitute in what we know
3785= pi x r^2 x 19
3785=59.69 x r^2
subtract 59.69 from both sides
3725.31=r^2
square root of 3725.31
61
square root of 61
= about 8
