The area of the circle:
A = r² π
The area of sector of a circle:
As = r² π ∙ θ / 360°
In this case:
As = 14² π ∙ 45° / 360° = 196 π ∙ 45° / 45° ∙ 8 = 196 π / 8 =
4 ∙ 49 π / 4 ∙ 2 = 49 / 2 π = 49 ∙ 3.14159 / 2 = 76.968955
As = 76.97 cm²
rounded on two decimal places

OR
45° / 360° = 1 / 8
As = 1 / 8 A = 1 / 8 r² π = 1 / 8 14² π = 196 ∙ 3.14159 / 8 = 76.968955
As = 76.97 cm²
