4 meters, since 100 centimeters equal 1 meter you'd divide 400 by 4 to get your answer of 4 meters. It's just basic math. Don't get so scared that you'll get your answer wrong and just focus.
Answer:
≈ 2,826 cm^3
Step-by-step explanation:
V = πr^2h
V = 3.14 · 10^2 · 9
V = 3.14 · 100 · 9
V = 314 · 9
V = 2,826
Answer:
A. -2 + 12 -2 ^ 3 + 2 ^ 0 * 3
= 10 - 2 ^ 3 + 2 ^ 0 * 3
= 10 - 8 + 1
= 3
B. 9 ^ (1/2)(25) - 8 + 2 + 3 ^ 2
= 9 ^ (1/2)(25) - 6 + 9
= 3 ^ 25 + 3
= 3 ^ 25 + 3
= 847288609446
C. 1/2 * 3/5 * (2 ^ 3 - 6) + 1/5
= 1/2 * 3/5 * 2 + 1/5
= 3/5 + 1/5
= 4/5
Sorry I don't have enough time to deal with this problems, I believe that by using this formula you will easily come out with your answer. In the first one that has all sides you must use the law of cosines. Here is the formulas . Keep it because it is very helpful
