Sagot :

Answer:

Radius = 2 yd

Diameter = 4 yd

Step-by-step explanation:

circumference = 2[tex]\pi[/tex]r (where r is the radius)

if circumference = 4[tex]\pi[/tex], then

  4[tex]\pi[/tex] = 2[tex]\pi[/tex]r

⇒  4 = 2r

⇒  2 = r

⇒ radius = 2 yd

diameter = 2r

               = 2 x 2

               = 4 yd
