V=hpir^2
so
A:B=
4pi1^2:4pi2^2=
4pi1:4pi4=
4pi:16pi=
4:16=
1:4
the ratio of volume of A to B is 1:4
Answer:
12.5663706144
If necessary, and if your system/teacher allows it, just keep it down to 1-3 decimals.
Hope I could help! :D
4.99x2=9.98. 11.45x3=34.35. 9.98+34.35=44.33. 6% of 44.33 is 2.6598. 44.33+2.6598=46.9898. So the total is $46.99
The discriminant is the portion of the quadratic formula under the root sign: b²-4ac
A quadratic equation in standard form is ax²+bx+c=0. In your equation:
a=1, b=2, and c=6. Substituting them into the equation:
2²-4(1)(6)
=4-24
=(-20)
When the discriminant is negative there are two, imaginary solutions.
If the discriminant equals a positive, perfect square number (like 4, 9, 16, etc), there will be two, rational roots.
If the discriminant equals a positive, nonperfect square number (like 3, 15, 23, etc), there will be two, irrational roots.
If the discriminant equals 0, there will be one double root
A quadratic equation graphs a parabola. The graph of a quadratic with a positive discriminant will pass through the x-axis twice. If the discriminant is 0, it will touch the x-axis and 'bounce' back the way it came. If the discriminant is negative, it will not touch the x-axis.
