Explanation:

First I translated this into English.

"Find the circumference of a circle whose diameter is 18 cm."

Formula:

C = 2πr

Translated in Spanish:

Primero tienes que dividir la circunferencia por dos. Luego lo enchufas en la fórmula para "R" y resuelves.

English Translation:

First you have to divide the circumference by two. Then you plug it into the formula for "R" and solve.
