Question
Dhamu fixes a square tile of 30 cm on the floor. The tile has a sector design on it as shown in the figure. Find the area of the sector. (π = 3.14)
Solution
Side of the square = 30 cm
∴ Radius of the sector design = 30 cm
Given the design of a circular quadrant.
Area of the quadrant = `1/4 pi"r"^2 "sq.units"`
= `1/4 xx 3.14 xx 30 xx 30 "cm"^2`
= 3.14 × 15 × 15 cm2
∴ Area of the sector design = 706.5 cm2 .....(approximately)
