There were 16 boys
-5:4, 10:8, 15:12, 20:16
-20:16 is 20+16=36
-20 were girls and 16 were boys
Answer:
756π cm^3.
Step-by-step explanation:
Volume of the cone
270π = 1/3 π r^2 h
270π = 1/3 π r^2 * 10
r^2 = 270 / ( 10/3 )
r^2 = 81
r = 9 cm.
So the volume of the hemisphere = 1/2 * 4/3 * π * 9^3
= 486π cm^3.
So the volume of the whole solid = 270π + 486π
= 756 π cm^3.
The first question is a Statistical Question. This is because Statistical Questions are questions that can be answered with a percent, range or average. It could have many correct answers.
The Second one is a Non-Statistical Question. This is because this cannot be answered with a percent, range, or average.
2/5 because it is basically looking up at google.
It is very easy to know how to use this in fractions because it can help you learn a lot
