Answer:
653.45 cm3
Step-by-step explanation:
First calculate the volumes of both cylinders, the formula is pi x radius^2 x height.
so, big cylinder = 1256...cm3. small cylinder = 603...cm3
Then take away the large from small.
1256...-603...
Start by laying out 7 tiles, and then adding 3. Whatever that number of tiles is equals x.
x = 10
10 - 3 = 7
60
1/3
The number of people over 40 is 20 + 30 + 35 = 85.
So the probability is 85/255, which reduces to 1/3.
