Best ResponseYou've already chosen the best response.0okay great. so 4/3 pi r^3 = 4500 pi

Best ResponseYou've already chosen the best response.0what does 13500 equal to?

Best ResponseYou've already chosen the best response.0sorry i get the first part but i don't know what you mean whats it equal to

anonymous

Best ResponseYou've already chosen the best response.0okay lets start over. \[4/3 * \pi * r ^{3} = 4500 \pi\]

anonymous

Best ResponseYou've already chosen the best response.0so, \[r ^{3} = 4500 \pi / (\pi*4/3) = 4500*3/4 \]

Best ResponseYou've already chosen the best response.0okay which is 3375 right?

anonymous

Best ResponseYou've already chosen the best response.0and so the radius is?

anonymous

Best ResponseYou've already chosen the best response.0how did you get that?

anonymous

Best ResponseYou've already chosen the best response.0i looke at the formula

anonymous

Best ResponseYou've already chosen the best response.0idk is the radus 3375

anonymous

Best ResponseYou've already chosen the best response.0no. \[r ^{3} = 3375 \rightarrow r = ?\]

Best ResponseYou've already chosen the best response.0if x^3 is 8, what is x?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0okay x^3 means x cubed or x raised to the power 3. x is 2. 2 cube is 8. 2 raised to the power 3 is 8. In other words, 2 multiplied by itself 2 times is 8. i.e 8 = 2 times 2 times 2

Best ResponseYou've already chosen the best response.0sorry multiplied by itself 3 times.

anonymous

Best ResponseYou've already chosen the best response.02 is called the cuberoot of 8.

anonymous

Best ResponseYou've already chosen the best response.0similarly radius cubed is 3375. so radius is cube root of 3375.

anonymous

Best ResponseYou've already chosen the best response.0use your calculator to find the cube root of 3375. that is your radius.

Best ResponseYou've already chosen the best response.0do you know what square root is?

anonymous

Best ResponseYou've already chosen the best response.0sqrt(3 375) = 58.0947502

Best ResponseYou've already chosen the best response.0I was asking you if you know the concept of square root.

anonymous

Best ResponseYou've already chosen the best response.0ohhh so the answer is b 60 units

anonymous

Best ResponseYou've already chosen the best response.0leave the problem for a moment. Do you know the concept of square root?

anonymous

Best ResponseYou've already chosen the best response.0okay. if you multiply a number by itself. it will give you another number. For example, if you multiply 4 by itself, that is, multiply 4 by 4, you get 16.

anonymous

Best ResponseYou've already chosen the best response.016 is the square of 4.

anonymous

Best ResponseYou've already chosen the best response.0and 4 is the square root of 16.

Best ResponseYou've already chosen the best response.0do you know the area of a square?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0area of a square of side A is A*A. that is why this is called square and square root. anyway, thats not important,

anonymous

Best ResponseYou've already chosen the best response.0similarly, if you multiply a number by itself 3 times, you get another number. so if you multiply 4 by itself thrice, that is 4 times 4 times 4, you get 64.

anonymous

Best ResponseYou've already chosen the best response.064 is the cube of 4. conversely, 4 is the cube root of 64.

anonymous

Best ResponseYou've already chosen the best response.0okay so, if the radius is multiplied by itself 3 times, you get 3375. so, radius*radius*radius = 3375

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0so, to get radius, we need to find the cube root of 3375.

anonymous

Best ResponseYou've already chosen the best response.0so r*r*r = 3375. 3375 lies between 1000 and 8000. so r must lie between 10 and 20. So, r is 15 units.
