Question

I can't figure this one out...

Answer 1

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

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

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

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

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.
