"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.
