(Round your coefficients to seven decimal places.) y = (b) Use the model in part (a) to approximate the area of the property in acres. (1 acre = 43,560 ft. Round your answer to one decimal place.) acre (c) Use the integration capabilities of a graphing utility to find the length (in ft) of the stream that bounds the property. (Round your answer to one decimal place.) ft
