PSLE The figure is formed by joining three 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 3 quarter circles
= 3 x 29.83
= 89.49 cm
Perimeter of the figure
= 89.49 + 6 x 19 - 4 x 5
= 89.49 + 114 - 20
= 183.49
≈ 183 cm
Answer(s): 183 cm
