The formula is V=1/3area of base*high
v=1/3*πr^2*h
=1/3*49π*9=49π*3=147πcm^3
a is the correct answer
Answer:
2/6 does NOT equal 6/10
Step-by-step explanation:
All of them can be simplified to equal each other except for that one.
9(x + 1)^4 - 19(x + 1)^2 + 2 = 0
After expanding and re-factoring, we have:
(3x + 2)(3x + 4)(x^2 + 2x - 1) = 0
solutions are x = -2/3, x = -4/3, x = -1 - sqrt(2), x = sqrt(2) - 1
I would choose lelia because she might have taken longer but maria ran 1 lap lelia ran 3 so lelia can run 2 1/4 (or (1/3) times faster
