Find the circumference and the area of a circle with diameter
2ft

Circumference: 6.28 feet ~rounded to the nearest hundredth

To find circumference, multiply the diameter by pi.

Area: 3.14 feet squared ~rounded to the nearest hundredth

To find area, divide the diameter by 2 and multiply by pi.

C = Pi x diameter.
C = 3.14 x 2
C = 6. 28

A = Pi x radius^2 
Radius = 1/2diameter
Radius = 1
Area = (3.14)(1^2)
Area = 3.14

Finding the area and circumference of a circle is pretty easy, actually. You just need to be comfortable with the formulas. Hope this helped!

14 is the best answer can i get brainliest?

Answer:

$4034.40

step-by-step explanation:

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
