Answer:
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
The circumference is equal to π × diameter.
3.14 × 5
= 15.7
The circumference of the circular post is 15.7 feet.
C) 1/6y+1/6(y+12)-2
x = hours 25 per hour = 25x
y = total
so y = 25x +140
D. (2x)(3x) + 5(3x - 2)
