z = 27

Step-by-step explanation:

Given that z² is proportional to x³ then the equation relating them is

z² = kx³ ← k is the constant of proportion

To find k use the condition z = 8 when x = 4, thus

8² = k × 4³

64 = 64k ( divide both sides by 64 )

k = 1

z² = x³ ← equation of proportion

When x = 9, then

z² = 9³ = 729 ( take the square root of both sides )

z = = 27

answer: 2530

hope this

just take the area of the square and then the area of the circle then subtract the circle area from the squares area
