A:
Answer:[tex]A1=28.3\ m^{2}[/tex],[tex]A2=78.5\ m^{2}[/tex],[tex]A3=132.7\ m^{2}[/tex]Step-by-step explanation:we know thatThe area of a circle is equal to[tex]A=\pi r^{2}[/tex]Part 1) Find the area of the circle with diameter 6 mwe have[tex]r=6/2=3\ m[/tex] -----> the radius is half the diametersubstitute the values[tex]A1=(3.14)(3)^{2}=28.3\ m^{2}[/tex]Part 2) Find the area of the circle with diameter 10 mwe have[tex]r=10/2=5\ m[/tex] -----> the radius is half the diametersubstitute the values[tex]A2=(3.14)(5)^{2}=78.5\ m^{2}[/tex]Part 3) Find the area of the circle with diameter 13 mwe have[tex]r=13/2=6.5\ m[/tex] -----> the radius is half the diametersubstitute the values[tex]A3=(3.14)(6.5)^{2}=132.7\ m^{2}[/tex]
