Answer:
32
/3 cm³
Step-by-step explanation:
If the diameter is 4 cm, then the radius is 2 cm.
Use the sphere volume formula:
V = 4/3
r³
Plug in the radius and solve:
V = 4/3
(2)³
V = 4/3
(8)
V = 32
/3
So, the volume of the sphere is 32
/3 cm³
total number of cards: 12 + 27 + 91 = 130
total number of cards with a circle: 91
so you have a 91/130 probability which reduces to 7/10 probability
First: 5
Second: 8
Third: 14
Hope this helps! :)
