Ad libitum [116K]

Answer:

8.04 units

Step-by-step explanation:

By Pythagoras Theorem:

${x}^{2} = \bigg( \frac{25.2}{2} \bigg)^{2} - {(9.7)}^{2} \\ \\ {x}^{2} = ( 12.6)^{2} - {(9.7)}^{2} \\ \\ {x}^{2} = 64.67 \\ \\ x = \sqrt{64.67} \\ \\ x = 8.04176598 \\ \\ x \approx \: 8.04$

What is the effect on the volume of a sphere if the radius is divided by 3?

Neko [114]

For this case we have by definition, that the volume of a sphere is given by:

$V = \frac {4} {3} \pi * r ^ 3$

Where:

r: It is the radius of the sphere

If the radius is divided by 3 we have:

$\frac {r} {3}:$

$V = \frac {4} {3} \pi * (\frac {r} {3}) ^ 3\\V = \frac {4} {3} \pi * \frac {r ^ 3} {27}\\V = \frac {4} {81} \pi * r ^ 3$

ANswer:

the volume decreases considerably because the denominator increases
