Answer:
28.27 ft²
Step-by-step explanation:
[tex]A=\pi r^2[/tex] where [tex]r[/tex] is the radius
Plug in 3 for the radius
[tex]A=\pi (3)^2\\A=9\pi[/tex]
[tex]A=28.27[/tex] (approximate answer when rounded to the nearest hundredth)
Therefore, the area of the circle is 28.27 ft².
I hope this helps!
Answer:
exact area: 9 ft²
approximate area: 28.3 ft²
Step-by-step explanation:
An area cannot be in feet. It must be in a square unit such as square feet.
A = r²
A = ()(3 ft)²
A = 9 ft²
A = 9(3.14159) ft^2 = 28.3 ft²
Answer:
exact area: 9 ft²
approximate area: 28.3 ft²
