Gnoma [55]

Answer:

$9.92 (rounded off to nearest cent)

Step-by-step explanation:

Square of 7-inch radius pizza = $7^{2}$ = 49 inches

49 Inches = $6

Square of 9-inch radius pizza = $9^{2}$ = 81 inches

Given 49 Inches = $6

1 inch =$ $$(\frac{6}{49} \\)$

I will leave it as a fraction as it is not the final answer, rounding it off will result in a loss of accuracy.

81 Inches = $81* \frac{6}{49} \\$

= $9.92 (rounded off to nearest cent)
