A wheel revolves twice in 16.5 ft., and going around a circular portion of land, the wheel makes 200 revolutions.
Determine area of the land in acres.
Area of circle: Pi * R^2
Wheel revolves once in 8.25 ft.
Acre = 43560 sq. ft.
Not sure how to solve.
:
Find the circumference of the land
200 * 8.25 = 1700 ft
Find the radius from this
2%2Api%2Ar = 1700
r = 1700%2F%282%2Api%29
r = 270.5634 ft is the radius
Find the area
A = pi%2A270.5634%5E2
A = 229978.9 Sq/ft
Change to acres
229978.9%2F43560 = 5.28 acres
