Diameter - 50 cm
Height - 0.9 m
[Ensure you have matching units!]
2*(pi*0.252) + 2*pi*0.25*0.9
= 1.806 m3
(or 18,064.158 cm3)

A set of 5 numbers is unknown. The stats are given below.
Mean = 4
Median = 3
Mode = 2
Range = 6
Find the five numbers, you have 1 minute.
3 must be in the middle..
2 must be there at least twice..
An 8 will give a range of six..
We need a mean of 4 (15 + x)/5 = 4
the set is 2, 2, 3, 5, 8

There are two rectangular prisms.
The dimensions of the larger prism are double the dimensions of the smaller prism.
If the smaller prisms volume is 10m3. What is the volume of the larger prism?
The dimensions of the smaller prism must be 5m, 2m, and 1m.
Doubling these is 10m, 4m, and 2m.
The volume would be 10 x 4 x 2 = 80 m3

On the board, draw a probability tree which shows flipping a weighted coin and then rolling and a die. It must be fully detailed.
The chance of getting heads on the coin is 0.25
Find the probability of getting an even number on the die, given that you get tails on the coin.
Tree must include probabilities on individual branches.
Calculation, given that the coin flip gives tails, and we're only inspecting the die roll, the chance is 3/6.
