Acircular rug has a diameter of 6 feet. what is the circumference of the rug? use 3.14 for π.

a) 9.42 ft
b) 18.84 ft
c) 28.26 ft
d) 37.68 ft

your answer is b. 18.84ft

Step-by-step explanation:

18.84 is the correct answer

Step-by-step explanation:

18.84 ft is the correct answer. Use the formula C = πd, where π ≈ 3.14 and d = 6 ft:

C = πd = (3.14)(6) = 18.84 ft

It must have the same slope as the given line, so

m = -A/B = -1/-2 = 1/2

So far, we have

y = mx + b = x/2 + b

Use the given point to find b.

4 = -2/2 + b = -1 + b

b = 5

y = x/2 + 5

Multiply through by 2.

2y = x + 10

Standard form:

x - 2y = -10
