PSLE The figure is formed by joining three 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 3 quarter circles
= 3 x 26.69
= 80.07 cm
Perimeter of the figure
= 80.07 + 6 x 17 - 4 x 5
= 80.07 + 102 - 20
= 162.07
≈ 162 cm
Answer(s): 162 cm
