Question

A cathedral has a large, circular stained-glass window. It has a diameter of 16 yards. What is the window's area?

Use 3.14 for ​.

Answer 1

A=200.96

Explanation:

We know that the diameter is 16, so that means the radius will be 8.

The formula for area of a circle is A=πr^2.

Therefore, we can plug our value of r (radius 8) into the equation while using 3.14 for pi (π) : (3.14)(8)^2.

Which comes out to 200.96
