Answer:
Step-by-step explanation:
the variable n would have to be less then zero.. answer 1
The correct answer is 14/15. To answer this problem, it would help to change the mixed number into an improper fraction.
1 1/3
4/3 Multiply 3 by 1, and then add 1 and put 4 over 3.
4/3 x 7/10 Now, multiply both numbers by each other. Since we're multiplying, we don't need to find a least common denominator.
28/30 4 x 7 = 28; 3 x 10 = 30
14/15 Since 28 and 30 are divisible by 2, we need to simplify the answer.
The correct answer is 14/15.
Hope this helps!

Answer:
5575 cm³
Step-by-step explanation:
The volume of a sphere is V = (4/3)πr³. If we substitute r = (d/2 where r is the radius and d the diameter), this formula becomes:
πd³
V = (4/3)π·d³/8, or V = -------------
6
and so, if d = 22 cm, the volume is:
π(22 cm)³
V = ------------------- = 5575 cm³
6
Answer:
V=( 1/6 )* π * d³
Step-by-step explanation:
We khow that d= 2r⇒ r=d/2
- so r³= d³/8
- substitute r with d³/8
- V= (4/3)*π*(d³/8) = (4/3*8)*d³*π = (1/6 )* d³ *π
