Question

If the radius of the window is 1 foot​, what is the area of the​ glass?

Answer 1

Hi there!

I'm going to assume that this is a circle window. To solve, we'll use the formula for the area of a circle: A = pi x r^2. We'll first plug in the radius, then solve for the area, leaving it in terms of pi. If you need a decimal, you can multiply the number by pi to get the decimal.

WORK:
A = pi x 1^2
A = 1pi
The area of the window is 1pi

Hope this helps!! :)
