Step-by-step explanation:
Answer:
24
Step-by-step explanation:
2.5 divided by 2.5 equals 1. So 60 divided by 2.5 equals 24.
Formula for volume of sphere V = 4/3 (Pi) r^3, where Pi ~ 3.14 and r is the radius = 7.
Therefore V = 4/3 * 3.14 * 7^3
= 4/3 * 3.14 * 343
= 4/3 * 1077.02
= 1,436.02667 cubic units
1.50y(2)+2.00x=20
Now use the quadratic formula to solve
