The area of the shaded sector RST is 8π unit²
What is area?
Area is the amount of space occupied by a two dimensional shape or object.
The area of a circle is given by:
A = π(radius)²
The circle has radius of 4 unit and angle of π radians. Hence:
Area of sector RST = (angle/2) * radius²
Area of sector RST = (π/2) * 4² = 8π unit²
The area of the shaded sector RST is 8π unit²
