QuestionCalculate the area of a ring with inner radius 18m and outer radius 22m. Use the formula for area: A=π(R2r2)A = \pi(R^2 - r^2).

Studdy Solution
Calculate the area of the shaded region.
Areashaded=484πm2324πm2=160πm2Area_{shaded} =484\pi m^2 -324\pi m^2 =160\pi m^2The area of the shaded region of the ring-shaped figure is 160π160\pi square meters.
