The circumference of the circle with diameter 132 cm to 1 d.p is 414.5 cm.
What is the circumference of the circle?
Diameter = 132 cm
Radius, r = Diameter / 2
= 132 cm / 2
= 66 cm
Circumference of a circle = 2 × π × r
= 2 × 3.14 × 66
= 414.48 cm
Hence, the circumference is approximately 414.5 cm to 1 d.p
