if the volume of a shere is 10293.33 cm^3, what is the diameter? Use 3.14 to approximate n. Round answeres to the nearest hundreth.

Question

callisto · Answer

Apply the formula $V=\frac{4}{3} \pi r^3$. Put V=10293.33 and $\pi = 3.14$ into the formula.
$$10293.33=\frac{4}{3} (3.14) r^3$$Now, can you solve r?

anonymous · Answer

is your r 4.186?

callisto · Answer

Nope...

anonymous · Answer

so how do you solve it then ?

callisto · Answer

First, divide both sides by 4/3
Next, divide both sides by 3.14
Lastly, take cube root for both sides.

anonymous · Answer

ok hold on

anonymous · Answer

13.50 using Callisto's equation.

anonymous · Answer

callisto i did that and i got the wrong answer can you show me ?

anonymous · Answer

Show your steps so we can help you find out where you went wrong. Do you have an answer guide BTW?

callisto · Answer

$$10293.33=\frac{4}{3} (3.14) r^3$$$$7719.9975=(3.14) r^3$$$$2458.59793= r^3$$$$r=13.50$$

callisto · Answer

I think you should show your steps too, just as @Wired said.

anonymous · Answer

where i went wrong was i did
(4/3)*10293.33 = 4/3(4/3)

callisto · Answer

Ah... Divide both sides by 4/3 is actually multiply both sides by 3/4

callisto · Answer

BTW, what you've found is the radius only!!!!
Diameter = radius x 2!
