What is the circumference of a circle with radius 4 cm?

16 cm
64 cm
8 cm
32 cm

The correct answer is: 32 cm

The circumference of a circle is the distance around the edge of the circle, and it is calculated using the formula C = 2πr, where r is the radius of the circle. In this question, the radius is given as 4 cm. So, using the formula, we get C = 2π(4) = 8π cm. Option A (16 cm) and C (8 cm) are incorrect as they do not use the appropriate formula to find the circumference. Option B (64 cm) is incorrect as it is the incorrect unit of measurement. Option D (32 cm) is incorrect as it uses the incorrect value for π (pi). Therefore, the correct answer is D (8π cm) as it is the correct calculation and unit of measurement for the circumference of a circle with a radius of 4 cm.
