Step-by-step explanation:
You know that:
- Eric need 1/2 deck of playing cards.
- Eric has 2/7 of a deck.
Therefore, to find the fraction of a deck that Eric still needs, you must subtract 1/2 and 2/7:
- Find the least common multiple of the denominators:
- Now, you can make the subtraction:
Therefore, he still needs of a deck.
Answer:
volume= 56.55 yds
Step-by-step explanation:
If you're looking for the volume, the formula is .
Diameter is two times the radius (radius is half of the diameter) so the radius of the cylinder would be 1.5 yds.
After you've gotten that information, plug those values into the formula.
Solve 1.5^2 first. Then multiply that value by pi. Then multiply that value by the height which is 8yds.
Volume=56.55yds rounded to the nearest hunderedth.
