The answer is  17,182.08 cm³
 
To calculate this we need to calculate the volume of each ball V2 - V1 = ?
The volume of a sphere with radius r is:
V = 4/3 π r³

Ball 1:
r1 = 18 cm
V1 = 4/3 * 3.14 * 18³
V1 = 24,416.64 cm³


Ball 2:
r2 = 12 cm
V2 = 4/3 * 3.14 * 12³
V2 = 7,234.56 cm³

<span>How much more water is in the larger balloon than in the smaller balloon:
V2 - V1 = </span>24,416.64 cm³ - 7234.56 cm³
             = 17,182.08 cm³

(ab^2 x -b^4a^3)^2<br><br> What is the answers
Umnica [9.8K]

Answer:

\left(ab^2x-b^4a^3\right)^2:\quad a^2b^4x^2-2a^4b^6x+a^6b^8

Step-by-step explanation:

Given the expression

\left(ab^2\:x\:-b^4a^3\right)^2

solving the expression

\left(ab^2\:x\:-b^4a^3\right)^2

\mathrm{Apply\:Perfect\:Square\:Formula}:\quad \left(a-b\right)^2=a^2-2ab+b^2

a=ab^2x,\:\:b=b^4a^3

so the expression becomes

=\left(ab^2x\right)^2-2ab^2xb^4a^3+\left(b^4a^3\right)^2

=a^2b^4x^2-2a^4b^6x+a^6b^8

Thus,

\left(ab^2x-b^4a^3\right)^2:\quad a^2b^4x^2-2a^4b^6x+a^6b^8

erik [133]
I'm pretty sure that the answer is 12C4 = (12p4)/4! = (12*11*10*9)/4*3*2*1 = 495

Hope this helps
