and i think i did it wrong too here is the problem:a cow is tied to a silo with radius r by a rope just long enoug to reach the opposite side of the silo find the the area available for grazing by the cow. thanks . :Dbtw this is for calculus bc people...
First you need to calculate the length of the rope: l = 0.5 * pi * r * 2 l = pi * r So the total area is the area of a circle with radius pi * r: area = pi * (pi * r)? = pi? * r? You might need to substract the area of the silo from this value, which is pi * r?. Result: pi? * r? - pi * r? = (pi? - pi) * r? = 27.819 * r?
