1. Problem Description

A circular window on a ship has a radius of 8 inches. We need to find the area of the glass needed for the window and round the answer to the nearest hundredth.

2. Solution Steps

The area of a circle is given by the formula:
Area=πr2Area = \pi r^2
where rr is the radius of the circle.
In this problem, the radius r=8r = 8 inches. Substituting this into the formula gives:
Area=π(82)=64πArea = \pi (8^2) = 64\pi square inches.
To find the numerical value, we can use the approximation π3.14159\pi \approx 3.14159. Then
Area=64×3.14159201.06176Area = 64 \times 3.14159 \approx 201.06176
Rounding to the nearest hundredth gives 201.06201.06 square inches.

3. Final Answer

201.06
