The cookie has a diameter of 11 inches and a height of 1.25 inches. Solve for the volume of the cookie.

To calculate the volume of the cookie, we need to use the formula for the volume of a cylinder:

Volume = πr^2h

where r is the radius of the cookie and h is the height of the cookie.

Given that the diameter of the cookie is 11 inches, the radius (r) is half of the diameter, so r = 11/2 = 5.5 inches.

Plugging in the values for r and h into the formula, we get:

Volume = π(5.5)^2(1.25)
Volume = π(30.25)(1.25)
Volume = 37.8125π

Therefore, the volume of the cookie is approximately 118.82 cubic inches, or 37.81π cubic inches.
