Find the area of the circle

113.04

Step-by-step explanation:

Since the diameter of a circle is twice the radius, the radius of this circle must be 12/2=6ft. Using the area formula:

Hope this helps!

113.04

Step-by-step explanation:

area = (pi)r^2

r = radius = diameter/2

r = 12 ft/2 = 6 ft

area = 3.14 * (6 ft)^2

area = 3.14 * 36 ft^2

area = 113.04 ft^2

$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
