Answer:

Area of the circle=[tex]100\pi[/tex] square units

Step-by-step explanation:

Circumference of the circle = [tex]20*\pi[/tex]

Finding the radius of the circle by using the formula of the circumference of the circle;

Circumference of a circle = [tex]2*\pi *r[/tex]

[tex]20*\pi[/tex] = [tex]2*\pi *r[/tex]

Dividing by '[tex]\pi[/tex]' both side:

[tex]20=2*r[/tex]

Dividing by '2' both side:

[tex]r=20/2\\[/tex]

[tex]r=10units[/tex]

Radius= 10 units

Area of the circle= [tex]\pi *r*r[/tex]

                      [tex]=\pi *10*10[/tex]

                      [tex]=100*\pi[/tex]

Area of the circle=[tex]100\pi[/tex] square units
