Answer:

$Blue = \frac{8}{9}$

Step-by-step explanation:

Given

$Yellow = 1ft^2$

$Blue = 8z^{-1$

Required

Evaluate Blue when z = 9

To do this, we simply substitute 9 for z in $Blue = 8z^{-1$

$Blue = 8 * 9^{-1$

Convert indices to fraction

$Blue = 8 * \frac{1}{9}$

$Blue = \frac{8}{9}$

Hence, the blue section has an area of $\frac{8}{9}ft^2$

Step-by-step explanation:

Formula:

$\boxed{a = 3.14(r)^{2} }$

r represents the radius.

The radius is 1/2 of the diameter.

Since 1/2 of 16 is 8, 8 is our radius.

Substitute:

$a = 3.14(8)^{2}$

Solve:

$a = 3.14(64)$

$a = 200.96in^{2}$
