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
Answer:
Yes he is correct, If it was 100% then it would stay the same 10 hours. But since it's 110%, it is in fact 11.
Step-by-step explanation:
The speed of a bus that travels 250 km in 2 hours is 145 because you have to divide 250 km and 2 hours which gives 145.
Hope this helps:)
Answer:
the fourth one
Step-by-step explanation:
3 times (2x + 5) is 6x + 15.
6x + 15 = 9 + 3x.
Group by like terms. 6 = -3x
Divide to get x by itself. 6/-3 = -2
Thus -2 = x
