Determine the volume of a cube with side lengths of 2 1/4 cm.
jeka94

The formula for volume of a cube is V = S^3 where S is the length of a side.

Volume = 2 1/4^3

Volume = 2 1/4 x 2 1/4 x 2 1/4

Volume = 11 25/64 as a fraction or 11.390625 as a decimal.

Andy has a snowball (a perfect sphere) with the radius of 3 cm. He wanted the snowball to be bigger, so he spent four seconds pa
BigorU [14]

Answer:

Ratio = \frac{64}{27}

Step-by-step explanation:

Volume of Sphere is given by the formula:

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

Where

V is the volume

and

r is the radius

Original Volume, given r = 3, would be:

V=\frac{4}{3} \pi r^3\\V=\frac{4}{3} \pi (3)^3\\V=\frac{4}{3}\pi (27)\\V=36\pi

Increased snowball volume:

Radius increased 0.25 per second, he spent 4 seconds, so radius increase:

0.25 * 4  = 1 cm

New radius = 3 + 1 = 4 cm

New Volume would be:

V=\frac{4}{3} \pi r^3\\V=\frac{4}{3} \pi (4)^3\\V=\frac{4}{3}\pi(64)\\V=\frac{256\pi}{3}

Ratio of New Volume to Original would be:

Ratio=\frac{\frac{256\pi}{3}}{36\pi}=\frac{256\pi}{3}*\frac{1}{36\pi}=\frac{64}{27}

This is the ratio for current volume to original volume.

Answer:The answer are the red card(The second), A dependent event is an event that relies on another event to happen first.

Since he keep his first took red card,his probability to get another red card became lower,therefore it effects on what card he will take next.

the third one doesn't called a dependent event because it's a Dice,so the probability still the same

The fourth one doesn't count to,since he return back the marble.
