1.
Calculate the circumference of a circle with a radius of 5 cm.
[2 marks]2.
A circle has a diameter of 12 meters. Find its circumference.
[3 marks]3.
If the radius of a circle is doubled, how does its circumference change?
[2 marks]4.
Construct a circle with a radius of 3 cm and then find its circumference.
[3 marks]5.
A bicycle wheel has a radius of 0.35 meters. What is the length of the wheel's circumference?
[2 marks]6.
A circular garden has a circumference of 50 meters. What is its radius? (Use π ≈ 3.14)
[3 marks]7.
A sports track is 400 meters long in circumference. What is the radius of the track? (Use π ≈ 3.14)
[3 marks]8.
Identify and correct the mistake in the following solution: 'To find the circumference of a circle with radius 4 cm, multiply 4 by 2π, getting 8π. So, circumference = 8π ≈ 25.12 cm.'
