primero tenemos que la circunferencia de un circulo, en este caso un plato es, C=π.d
 
donde C= la circunferencia
π= 3,1416...
d= diametro

C=π.d

reemplazamos, 47,1=
π.d

despejamos d

d= 47.1/3,1416...
d=14.99 aproximadamente

luego tenemos que el diametro es 14.99 y como el radio es la mitad dividimos entre dos

14.99/2

r=7,49 pulgadas

The formula for this problem is r=C/2π
r=47.1/2π. 47.1/2π= 7.5
So r=7.5
