PSLE The figure is formed by joining two 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 2 quarter circles
= 2 x 25.12
= 50.24 cm
Perimeter of the figure
= 50.24 + 4 x 16 - 2 x 5
= 50.24 + 64 - 10
= 104.24
≈ 104 cm
Answer(s): 104 cm
