Answer:

=[tex]12.25[/tex][tex]\pi[/tex]

Step-by-step explanation:

Given:

Length of  butcher paper,(diameter of three congruent circle) = 21 inches

Means, diameter of a circle = [tex]\frac{21}{3}[/tex] = 7 inches

Questioned asked:

Area of one circle = ?

Solution:

Radius of a circle ,r = half of of one circle's diameter

                           r = [tex]\frac{7}{2}[/tex]

                            = [tex]3.5[/tex]

Area of circle = [tex]\pi[/tex][tex]r^{2}[/tex]

                      [tex]3.5\times3.5[/tex] [tex]\pi[/tex]

                      =[tex]12.25[/tex][tex]\pi[/tex]

                     

  Therefore, Area of one circle   ==[tex]12.25[/tex][tex]\pi[/tex]
