Question

si el radio de una pelota es de 12cm ¿cuál es su circunferencia maxima? ​

Answer 1

Respuesta:

Explicación:

Radius is

6

c

m

, circumference is

12

π

cm.

Explanation:

The diameter of a circle is two times the radius, or,

d

=

2

r

This means that the radius is one half of the diameter,

r

=

1

2

d

So, if

d

=

12

cm,

r

=

1

2

(

12

)

=

12

2

=

6

cm.

The circumference is given by

c

=

2

π

r

. We know

r

=

6

,

so

c

=

2

π

(

6

)

=

12

π

cm
