PSLE The figure is formed by joining three quarter circles of radius 16 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 16
= 32 cm
Circumference of the quarter circle
=
14 x 3.14 x 32
= 25.12 cm
Circumference of 3 quarter circles
= 3 x 25.12
= 75.36 cm
Perimeter of the figure
= 75.36 + 6 x 16 - 4 x 5
= 75.36 + 96 - 20
= 151.36
≈ 151 cm
Answer(s): 151 cm
