What is the rule that describes this pattern of numbers -10,000; -1,000; -100; -10; -1; -0.1; -0.01; -0.001

9.0 inches

Step-by-step explanation:

Area of square pan should be equal to area of circle pan

Area of square is 8 * 8 = 64

Area of Circle is

Using 3.14 as   and given that area must be 64, we solve for 4:

We know diameter is twice of radius, so diameter is  

Hence, diameter should be 9.0 inches (rounded to nearest tenth)
