PSLE The figure is formed by joining three quarter circles of radius 14 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 14
= 28 cm
Circumference of the quarter circle
=
14 x 3.14 x 28
= 21.98 cm
Circumference of 3 quarter circles
= 3 x 21.98
= 65.94 cm
Perimeter of the figure
= 65.94 + 6 x 14 - 4 x 4
= 65.94 + 84 - 16
= 133.94
≈ 134 cm
Answer(s): 134 cm
