Question

The diameter of a circle is 100 cm. What is the circumference of the circle? (Use 3. 14 for π. )

Answer 1

Answer: 314 cm

Explanation:

Use the formula C = pi*d

We're multiplying 3.14 by the diameter 100 to get 314, which is the approximate distance around the circle (aka perimeter). The value is approximate because pi = 3.14 is approximate.
