the surface area ratio of solid a to solid b is 16:9 . If the volume of solid b is 243 m ^3 find the volume of solid A

432 m^2

Step-by-step explanation:

since a ratio is given, we can understand that this ratio was obtained by simplifying the values of the actual surface area of a and b.

so

16:9 = a:243

a = 243 x 16 divided by 9 = 27 x 16 = 432

{3 + i, 3 - i, 3, -1}

step-by-step explanation:

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
