Normally, to find the area of a circle you'd do π × [tex] r^{2} [/tex] so you have to find the radius by dividing 5 by 2 to get 2.5. Approximating pi as 3.14, you would do 3.14 × [tex] 2.5^{2} [/tex] = 19.625. Because the porch is a quarter circle, you would then divide this by 4 to get 4.906. Rounded to the nearest square foot, your answer would therefore be 5 ft. I hope this helps!
