AP An oil tanker aground on a reef is forming a circular oil slick about 0.1 foot thick. To estimate the rate (in cubic feet per minute) at which the oil is leaking from the tanker, it was found that the radius of the slick was increasing at 0.31 foot dR dv Tanker per minute ( -0.31) when the radius Rwas 400 feet. Find using x 3.14. A-ER V-01A -On / min av (Type an integer or a decimal. Round to the nearest whole number as needed.)
