You need to find the surface area and the volume. The formula for surface area is 4*3.14(pi)*radius^2 which is equal to 6.5144 inches^2 in this case. The amount of rubber needed to fill it is equal to the volume. The formula for volume of a sphere is 4/3*3.14(pi)*radius^3, just plug in the number (remember radius is half of diameter) and that will give you the answer!
If there are 10 wild cards there are 50 standard cards. 8 and 40 can both be divide by 4, which makes 2/10. This means that there are 2 wild cards for every 10 standard cards. If there are 50 wild cards, you simply multiply 2/10 by 5. This will give you 10/50. 10 wild cards in 50 standard cards.
Answer:
pathway will tell you the answer straight away so you dont have to depend on some1
This can be solve by cancel of units
Snice red/ bkue = 5/2
And bkue/ green = 3/ 5
So red/ green = (red/ bkue) x( blue/ green)
Red/ green = (5/ 2) x (3/ 5)
Red / green = 3 /2
So the ratio of red is to green is 3: 2
