676 cubic units
1,464.67 cubic units
2,929.33 cubic units
3,661.67 cubic units

Answer 1

I know the formula I just keep getting the wrong answer.

Answer 2

well then that means either u have the wrong formula or u dont plug in the right numbers

Answer 3

i did this in 7th grade so whats the formula cuz i kinda forgot lol

Answer 4

ill help ;)

Answer 5

I did the formula is V= 4/3*P or 3.14*r to the power of 3

Answer 6

@ganeshie8 @divu.mkr @ahamed.

Answer 7

whats the perimeter of the sphere

Answer 8

Idk

Answer 10

well then u cant figure out the 3.14*r cuz u need to know what the perimeter is i order to figure that part out i think...

Answer 11

But its just 3.14 times the radios to the power of 3.

Answer 12

yea but whats a radius... the half measurement of the perimeter

Answer 13

brb

Answer 14

The radius is half of the circumference the circumference is 26

Answer 15

Volume sphere = (4/3) * pi * r ^3

Volume = (4/3) * pi * (13)^3

Volume = 9202.77 cubic units which does not match any options.
