Solve the equation for the letter d: c equals pi multiplied by d

we know that

The formula to calculate the circumference of a circle is equal to

where

d is the diameter of the circle

Solve for d

That means------> isolate the variable d

Divide by both sides

therefore

the answer is

$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
