The answer is C, but I don't understand why- can anyone tell me?

finlep [7]

Answer:

It's C because we are adding a number on the x but here we skip 5 so it's 6, and on y we add 4 up but since we skipped 5 we add 8 and we get 24. 6, 24. You may say "but SpiritBear, 17 plus eight is 25" and that is true, but if you notice the lowest dot actually starts on 5, not 4 making C right.

Hope this helped and wasn't too confusing

A sphere and the base of a cone have a radius of 3 inches. The volume of the sphere equals the volume of the cone. what is the h

Valentin [98]

So the volume of a sphere is $V= \frac{4}{3} \pi r^3$ , and the volume of a cone is $V= \pi r^2 \frac{h}{3}$ (h=height, r=radius). Knowing only the radius, we can solve for the volume of the sphere. (Also I'm going to be leaving answers in pi form.)

$V= \frac{4}{3} \pi 3^3$
Solve the exponents to get $V= \frac{4}{3} \pi 9$
Multiply 4/3 and 9 to get $V=13.5 \pi$

Now that we know the volume of the sphere, we can solve for the height of the cone since the volumes for both are the same.

$13.5 \pi = \pi 3^2 \frac{h}{3}$

Solve the exponents to get $13.5 \pi =9 \pi \frac{h}{3}$

Divide $9 \pi$ on each side to get $1.5= \frac{h}{3}$

Multiply 3 on each side, and your answer should be $4.5=h$
