Answer: She has to score a minimum of 92 marks to take her average to 80
Step-by-step explanation:
Let the equation be
Three months total = 76 x 3 = 228

x + 228 = 80 x 4
x = 320 - 228
x = 92
Area of a cylinder is pi*r^2*h
The radius is half the diameter.
So the radius is 3.5
3.14*3.5^2*7=269.255 cubic meters.
The answer to the question is 8
