Aprehistoric site was discovered. the site is a nearly perfect circle, consisting of nine concentric rings that probably held upright wooden posts. around this timber temple is a wide, encircling ditch enclosing an area with a diameter of 437 ft. find this enclosed area to the nearest thousand square feet. use 3.14 for π.

The answer is 1350000 sq. ft.

Step-by-step explanation:  Given that a prehistoric site was discovered, which is nearly a perfect circle, consisting of nine concentric rings that probably held upright wooden posts. Around this timber temple is a wide, encircling ditch enclosing an area with a diameter of 437 ft. We need to calculate the enclosed area.

The radius of the encircling ditch is given by

So, the area of this encircling ditch will be

Since the site is consisting of 9 concentric rings, so the total enclosed area will be

Thus, the required area is 1350000 sq. ft.

the infinity sign
