A=2 pie r squared + 2 pie r h solve for h

Answers

Answer 1

Answer: A=2pie r^2 + 2pie rh so get h alone.
first take out the common factor of 2pie 2, so A=2pie r (r+h)
then divide by 2pie r, A/2pie r= r+h
then subtract r, so (A/2pie r) - r= h

A Pythagorean triple is a triple of natural numbers satisfying the equation a^2+b^2+c^2.One way to produce a Pythagorean triple is to add the reciprocals of any two consecutive even or odd numbers. For example, 1/5+1/7=12/35. Now 12^2+35^2=1369. This is a Pythagorean triple if 1369 is a perfect square, which it is since 1369=37^2. So 12, 35, 37 is a Pythagorean triple. Prove that this method always works.

Answers

Well, let's write it out, shall we? 6c2-5d+8 Now plug in the numbers. 6(5^2)2-5(4)+8 Now simplify using PEMDAS Parentheses Exponents Multiplication Division Addition and Subtraction (They go together go from left to right in the equation) 5^2= 5*5 = 25 6 * 25 = 150 150 * 2 = 300 5 * 4 = 20 Rewrite the equation. 150-20+8 Use PEMDAS again ( refer to the previous mentioning) 150 - 20 = 130 130 + 8 = 138

Answers

31,606,577

= 30,000,000 + 1,606,577

= 30,000,000 + 1,000,000 + 606,577

= 30,000,000 + 1,000,000 + 600,000 + 6,577

= 30,000,000 + 1,000,000 + 600,000 + 6,000 + 577

= 30,000,000 + 1,000,000 + 600,000 + 6,000 + 500 + 77

= 30,000,000 + 1,000,000 + 600,000 + 6,000 + 500 + 70 + 7
