Question

I can't figure this one out...

Answer 1

Answer:

the area would be 36(pi) since you can't find out the exact value of pi (22/7) and where it would terminate so thats the most exact answer you can get. The circumference would be

Step-by-step explanation:

12/2 = 6

Area = (pi)radius^2

6^2 = 36

36(pi)

Circumference: (pi)d

12(pi)

For approximate area you multiply r^2 by 3.14

For approximate circumference you multiply diameter by 3.14

Answer 2

Answer:

Exact: Area 36π ft^2  and Circumference 12π ft.

Approximate;  Area = 113.10 ft^2 and  Circumference 37.70 ft (to nearest hundredth).

Step-by-step explanation:

The diameter is 12 ft so the radius = 1/2 * 12 = 6 ft.

Area = π r^2

= 6^2 π  = 36π  ft^2. (exact).

Circumference =  2π r

= 12π  ft  (exact).

The approximate values are Area 113.10 and Circumference 37.70  to nearest hundredth.
