well if we know that Vs=4/3pir^3 then r=(Vs/1.33pi)^1/3

campbell_st · Answer

Well the formula is 

$$V = \frac{4}{3} \pi r^3$$ 

substitute your volume 

$$1349 = \frac{4}{3} \pi r^3$$

now solve for r...

don't use calculator

omg this is soo hard -_-

campbell_st · Answer

start by multiplying both sides by 3 to eliminate the denominator of 3

i dont have one that is why im asking.....

campbell_st · Answer

wellI I'll help you calculate it... but I won't give you the answer...

anonymous · Answer

ok

campbell_st · Answer

what did you get when you multiplied both sides by 3

anonymous · Answer

formula for volume is
$$V =4\pi r^3/3$$ 
then put the value of V in given formula that is

$$1349=4 \pi r^3/3$$
$$1349*3/(4*\pi)=r^3$$
then you will get your result.
