7.8 ft
15.7 ft
31.4 ft
19.6 ft

15.7

Step-by-step explanation:

Circumference = πd

π = 3.14

d = diameter (5 feet)

C = 3.14(5)

C = 15.7

15.7 feet

Step-by-step explanation:

The circumference is equal to π × diameter.

3.14 × 5

= 15.7

The circumference of the circular post is 15.7 feet.

answer: c i think

step-by-step explanation:

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363
