SA =  sq. in.
V =  cu. in.

anonymous · Answer

you know you know how to do this

anonymous · Answer

if i knew how do it i would have no asked :)

anonymous · Answer

Simply plug in the radius you are given into the formula for the SA and V

anonymous · Answer

of a sphere

anonymous · Answer

i dont know the formula it does not say

anonymous · Answer

$$A=4*\pi*r^2$$

anonymous · Answer

how can you not know the formula, it has been given to you more than twice in your other posts

anonymous · Answer

$$V=(4/3)*\pi*r^3$$

anonymous · Answer

$$now can you $$

anonymous · Answer

okay so i divide that forumal u gave me bye the numbers?

anonymous · Answer

no, you simply plug in the value of the radius into the formula and evluate it

anonymous · Answer

it may be simple for u but not for me

anonymous · Answer

plug your radius into r
and solve for v/A

anonymous · Answer

hes basically giving you the answer

anonymous · Answer

okay ill try it one second

anonymous · Answer

nope doesnrt work :/.

anonymous · Answer

what do you mean it dosent work??

anonymous · Answer

in each formula, when you see an r, plug in 4

anonymous · Answer

i got 12

anonymous · Answer

your r=4, do 4 to the 3rd power. 
4^3=64
64 * pie = 64π
64 * (4/3) = 85π =Volume

omg that makes since thank you :D
