QUESTION 4 fоr Grаdescоpe:The density оf oil in а circulаr oil slick on the surface of the ocean is given by f ( r ) = 30 4 + r kg/m 2 {"version":"1.1","math":"f(r)=frac{30}{4+r} text{ kg/m}^2"}where r is the distance in meters from the center of the slick. Which of the following can be used to find the total mass of the oil when the edge of the slick is 11 meters from the center? (Multiple choice: please select one of the options below.) A. ∫ 0 11 π ( 30 4 − r ) d r {"version":"1.1","math":"text{A.} int_0^{11} pi left(frac{30}{4-r} right) dr"} B . ∫ 0 11 121 π ( 30 4 − r ) d r {"version":"1.1","math":"B. ,,, , , int_0^{11} 121 pi left(frac{30}{4-r} right) dr"} C. ∫ 0 11 r ( 30 4 − r ) d r {"version":"1.1","math":"text{C.} ,,,,, , int_0^{11} r left(frac{30}{4-r} right) dr"} D. ∫ 0 11 ( 30 4 − r ) d r {"version":"1.1","math":"text{D.} ,,,,, , int_0^{11} left(frac{30}{4-r} right) dr"} E. ∫ 0 11 π r 2 ( 30 4 − r ) d r {"version":"1.1","math":"text{E.} ,,,,, , int_0^{11} pi r^2 left(frac{30}{4-r} right) dr"} F. ∫ 0 11 2 π r ( 30 4 − r ) d r {"version":"1.1","math":"text{F.} ,,,,, , int_0^{11} 2pi r left(frac{30}{4-r} right) dr"}
