The volume of a sphere is a 3/4 pi r^2 so we know the radius is 12 so 12 square is 144 pi 144*3=432 /4=108. volume is 108 pi cubed units
Step-by-step explanation:
45°+90°+60°+X°=360° (being complete angle)
or,195°+X°=360°
or,X°=360°-195°
or,X°=165°
Therefore,valueof X is 165°.
-2 5/12 - 3 2/3 + 1 1/2 =
- 29/12 - 11/3 + 3/2 =
-29/12 - 44/12 + 18/12 =
-73/12 + 18/12 =
- 55/12 or - 4 7/12 <===
The butterfly method. Multiply then divide
