V = 4/3 pi r^3

r^3 = 3V / 4pi

r^3 = (3 * 972pi) /(4pi)

r^3 = 729

r = 9

V = 4/3 π r³

Given that v = 972π

972π = 4/3 π r³

\\Multiply by 3 on both sides

2916π = 4 π r³

\\ Divide by 4π on both sides

729 = r³

\\cube root both sides

∛729 = r

9 = r

Answer: r = 9 inches

Please help !!!!! Explain to me and need answer quick

schepotkina [342]

Answer:

We can see that the denominators of both the numbers is not same

So in order to make it same for the both numbers, we will multiply the second number by 2/2 ,(which is basically 1 so it won't affect our calculations)

$\frac{11}{2^2 * 5^2}$ - $\frac{2}{2^2 * 5^2}$

So we will just subtract the numbers now

$\frac{9}{2^2 * 5^2}$ <em>This is the answer </em>
