Answer:
Part 1) The area is [tex]A=4,069.44\ in^{2}[/tex]
Part 2) The circumference is [tex]C=226.08\ in[/tex]
Step-by-step explanation:
step 1
Find the area
we know that
The area of a circle (circular tablecloth) is equal to
[tex]A=\pi r^{2}[/tex]
we have
[tex]r=72/2=36\ in[/tex] ------> the radius is half the diameter
[tex]\pi =3.14[/tex]
substitute
[tex]A=(3.14)(36)^{2}[/tex]
[tex]A=4,069.44\ in^{2}[/tex]
step 2
Find the circumference
we know that
The circumference of a circle (circular tablecloth) is equal to
[tex]C=\pi D[/tex]
we have
[tex]D=72\ in[/tex]
[tex]\pi =3.14[/tex]
substitute
[tex]C=(3.14)(72)[/tex]
[tex]C=226.08\ in[/tex]
