Please help I don't understand this at all..... on this would i do 82*pi/1:4, and 42*pi/1:8? The solid described is similar to a large solid with the given scale factor. Find the surface area and volume of a larger solid. A right prism with a surface area of 82 square feet and a volume of 42 cubic feet; scale factor 1:2: square

Best ResponseYou've already chosen the best response.0so how would i do 1:4

Best ResponseYou've already chosen the best response.0if the smaller solid has area of 82 then multiply by 4, if 82 refers to the larger then divide by 4 to get the smaller solids area.

Best ResponseYou've already chosen the best response.0i am assuming the ratio is 1:2 for side length

Best ResponseYou've already chosen the best response.0it just says the scale factor is 1:2

Best ResponseYou've already chosen the best response.0ok a prism with sides length twice as long will have 4X the area so we are ok

Best ResponseYou've already chosen the best response.0we only need to use pi when calculating area/perimeter/volume of a circle
