mayrabris2cute 2 years ago What is the area of a circle if the diameter is 12 feet?? Answers: a. 113.0 ft² b. 124.8 ft² c. 37.7 ft² d. 452.2 ft²

Area of a circle is A= (pi)*r^2

2. hartnn

$A =\pi d^2/4$ just plug in d =12

Thx @hartnn

4. hartnn

welcome ^_^

So its 3.14*144 = 452.16/4???

6. hartnn

you forgot to divide by 4.

|dw:1358452844870:dw|

Diameter is 2*r

9. hartnn

3.14*144 /4=

10. mayrabris2cute

?So no dividing??? I'm confused!! I just multiply by 2 or do I also divide by 4

11. GiGIgo3

yea divide by 4

12. mayrabris2cute

Ok.... Idk who is right, @hartnn , @cgreenwade2000 , or @GiGIgo3

13. hartnn

when you put d=12 you get A = 3.14 *144/4 = 113.0 that would be the answer :)

14. GiGIgo3

solve this 12x12=???.? ???.?x3.14 = ???? ???? / 4 = your answer
