So we know that the diagonals of a rectangle are equal than
3c/9 = 4 - c
c/3 = 4-c
c = 3(4-c)
c = 12 -3c
4c = 12
c = 12/4
c = 3
so in this case the length of AC = 3*3/9 = 9/9 = 1 and the length of
BD = 4 - 3 = 1
hope this will help you
You're given the diagonal decomposition of the matrix:
Computing the product yields
Answer:
the volume of cylinder = πr²h
h = 5cm
r = 6cm
volume = π × 6² × 5
= π × 6 × 6 × 5
= 180πcm³
Without rounding, I make it six. You could do it this way
54527/5^6 comes to a little over 3. That should be close enough. I'm going to check this by doing the divisions. I could let the computer do it, but I'd like to see if there's a pattern. There isn't and the correct answer is
6 <<<< divisions.
Answer:
3.15
