Answer:
A/B = 0.125
Step-by-step explanation:
Givens
r for Sphere A = 4
r for Sphere B = 8
Solution
Volume A = 4/3 pi r^3
r = 4
Volume A = 4/3 pi 4^3
Volume A = 4/3 pi 64
Note: there is no point in expanding the result. 4/3 and pi are going to cancel out when you set up the volume formula
Volume B = 4/3 pi * r^3
r = 8
Volume B = 4/3 pi * 8^3
Volume B = 4/3 pi * 512
Ratio A to B = 4/3 pi * 64 / 4/3 * pi * 512 Cancel 4/3 pi
Ratio A to B = 64/512
Ratio A to B = 1/8
Ratio A to B = 0.125
Answer:
a=75
Step-by-step explanation:
85^2-40^2=5625
then the square root of that is 75
Answer:
(-6, 0).
Step-by-step explanation:
x^2 + 36y^2 + 12x = 0
Convert to standard form:
(x + 6)^2 - 36 +36y^2 = 0
(x + 6)^2 + 36y^2 = 36
Divide through by 36:
(x + 6)^2 / 36 + (y - 0)^2/ 36 = 1
Now compare this with the general form:
(x - h)^2/a^2 + (y - k)^2/ b^2 = 1
We see that the center (h, k) = (-6, 0).
