PSLE The figure is formed by joining two 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 2 quarter circles
= 2 x 21.98
= 43.96 cm
Perimeter of the figure
= 43.96 + 4 x 14 - 2 x 4
= 43.96 + 56 - 8
= 91.96
≈ 92 cm
Answer(s): 92 cm
