Best ResponseYou've already chosen the best response.0no problem, i might have to hop back and forth with another person lol

Best ResponseYou've already chosen the best response.0SO for 22, the lighter sphere's diameter is 4, and the shaded sphere is 12

Best ResponseYou've already chosen the best response.0do you know the sphere volume equation?

Best ResponseYou've already chosen the best response.0as for the question itself, you just find the volumes, and subtract from each other

Best ResponseYou've already chosen the best response.0But remember it is DIAMETER, and we want RADIUS, and to get that, we divide the diameter by 2

Best ResponseYou've already chosen the best response.0Then you just plug the values of the radius for the equation and find both, then subtract to find your answer!, find it and i will check

Best ResponseYou've already chosen the best response.0no, one of the diameter is 4, and one is 12

Best ResponseYou've already chosen the best response.0so find the radius of them both! and then plug them in

Best ResponseYou've already chosen the best response.0so I do 4/3 * 3.14 * 6^3 ?

Best ResponseYou've already chosen the best response.0And you would do the same for the other sphere, whose diameter is 4

Best ResponseYou've already chosen the best response.0and I get 1657.92  33.49 ?

Best ResponseYou've already chosen the best response.0How did you get 1657.etc

anonymous

Best ResponseYou've already chosen the best response.0I plugged 4/3 * 3.14 * (6)^3

Best ResponseYou've already chosen the best response.0hmmm, well 4/3= 1.3333333.... 1.3333.....x3.14 (personally like to use pi but whatever :P)=4.18666666... So then 6^3 equals 216 so 4.1866666666X216=904.32

Best ResponseYou've already chosen the best response.0Wow xD blonde moment there! Can you help with the other if you have the time? XD

Best ResponseYou've already chosen the best response.0yea! so we know how to find the shaded area quickly, because volume of rectangular prism is l x w x h

Best ResponseYou've already chosen the best response.0Do you know the cylinder volume formula

anonymous

Best ResponseYou've already chosen the best response.0So we already know the height and radius. To know these you have to image a bit. The circle/ends of the cylinder take up the whole ends of the prism except for those slivers. The diameter would just be one of the sides, which is 8 in this case. Then we find the radius which is 4

Best ResponseYou've already chosen the best response.0and to find the hieght it is the length of the prism, which is, you guessed it, 32

Best ResponseYou've already chosen the best response.0so then we just subtract the volumes from each other
