Question

Find the area inside the 26m square and outside the circle. Use 3.14 for π. A circle is fully inside a square with sides of length 26 meters, such that the circle touches the center of each side of the square.

Answer 1

A(b) = 145,34 m²

Explanation:

Area of the square of side l = 26 m A(s) = l² A(s) = (26)²

A(s) = 676 m²

Areaof the circle of radius r = 13 A(c) = π*(r)² A(c) = π*(13)²

A(c) = 169*π m²

Then the area outside the circle and inside the square A(b), is the difference between the area of the square minus the area of the circle, that is:

A(b) = A(s) - A(c) = 676 - 169*π m²

A(b) = 676 - 530,66 m²

A(b) = 145,34 m²
