A farmer purchased a large circular field with an area of 1,017.36 square yards to build a farm. The farmer wants to walk the fence around the entire perimeter to make sure it is secure. How many yards will he/she be walking?
Please show all work.

113.04feet

Step-by-step explanation:

Area of the circular field  = πr²

r is the radius

Given

Area = 1,017.36 square yard

1,017.36 = πr²

r² = 1,017.36/3,14

r² = 324

r = √324

r = 18yds

Get the circumference

C = 2πr

C = 2(18)(3.14)

C = 113.04yds

Hence he/she must have been walking for 113.04feet

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
