The diameter of a circle has endpoints at (3,1) and (11,7) find the radius

radius = 5 units

Step-by-step explanation:

The radius r is the distance from the centre to either of the 2 endpoints of the diameter.

Calculate the centre C using the midpoint formula

C = ( , ) = (, ) = (7, 4 )

Using the distance formula

r =

with (x₁, y₁ ) = C (7, 4 ) and (x₂, y₂ ) = (11, 7 )

r =

  =

  =

   =

   = 5

step-by-step explanation:

if x = 2 you have to find x to finish the problem

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
