PSLE The figure is formed by joining two quarter circles of radius 19 cm. Find the perimeter of the figure. Round your answer to the nearest whole number. Take π = 3.14
Diameter of the quarter circle
= 2 x 19
= 38 cm
Circumference of the quarter circle
=
14 x 3.14 x 38
= 29.83 cm
Circumference of 2 quarter circles
= 2 x 29.83
= 59.66 cm
Perimeter of the figure
= 59.66 + 4 x 19 - 2 x 5
= 59.66 + 76 - 10
= 125.66
≈ 126 cm
Answer(s): 126 cm
