PSLE The figure is formed by joining two quarter circles of radius 17 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 17
= 34 cm
Circumference of the quarter circle
=
14 x 3.14 x 34
= 26.69 cm
Circumference of 2 quarter circles
= 2 x 26.69
= 53.38 cm
Perimeter of the figure
= 53.38 + 4 x 17 - 2 x 5
= 53.38 + 68 - 10
= 111.38
≈ 111 cm
Answer(s): 111 cm
