Answer:
About 113,097.34 units
Step-by-step explanation:
The volume of a sphere can be found with the equation V =
πr³ when r is the radius.
V =
πr³
V =
π(30)³
V ≈ 113,097.34 units
Answer: 
Step-by-step explanation:
If we draw RP and PS, then in the quadrilateral formed, we know that
, and since angles in a quadrilateral add to 360 degrees, this means
.
Thus, arc RS also measures 126 degrees
7 7/8 in mixed number form.
Number 7: 11/12-9/10 = 110/120-108/120=2/120= 1/60
number 8: 5/18-1/3=15/54-5/54=10/54 =5/27
