Answer 2

1)What is the exact circumference of a circle with a radius of 15 cm?

The circumference of a circle is calculated by the equation:

C = 2πr = 2π(15 cm) = 30π cm

2)What is the exact circumference of a circle with a radius of 16?

The circumference of a circle is calculated by the equation:

C = 2πr = 2π(16 cm) = 32π cm
