Answer:
16+(kx3)
Step-by-step explanation:
You add 16 to kx3
Let x=small circle
2x = bigger circle
πx^2 + π(2x)^2 = 80π
x^2 + 4x^2 = 80
5x^2 = 80
x^2 = 16
x = +/- 4
but we need the positive one because there's no negative measurement so
the answers are:
4m and 8m

Answer:
x = 5.4
Step-by-step explanation:
since the figures are scaled factors of each other then they are similar.
the ratios of corresponding sides are therefore in proportion, that is
= ( cross- multiply )
4x = 21.6 ( divide both sides by 4 )
x = 5.4
