Question 1 What is the circumference of a circle with a radius equal to 7?

1 answer

The circumference of a circle is given by the formula C = 2πr, where r is the radius of the circle.

Given that the radius of the circle is 7, we can substitute this value into the formula to find the circumference:

C = 2π(7)
C = 14π

Therefore, the circumference of a circle with a radius equal to 7 is 14π, or approximately 43.98 units.
