Answer:

4. Find the circumference of the circle. Round to the nearest hundredth.

21 ft

      65.97

5. Find the area of the circle. Round to the nearest hundredth.

      346.36

Answer:

C = 65.94 ft and A = 346.185 ft^2

Step-by-step explanation:

r = d/2 = 21/2 = 10.5

let [tex]\pi[/tex] = 3.14

C = 2[tex]\pi[/tex]r

C = 2(3.14)(10.5) = 65.94 ft

A = [tex]\pi[/tex]r^2

A = (3.14)(10.5)^2 = 346.185 ft^2
