Alejandra is filling a cylindrical tank with gasoline at a rate of 20 cubic feet per minute. The radius of the tank
is 10 ft and height is 8 ft. How many minutes will it take
to fill the tank to the top?
Round to the nearest hundredths, if necessary

answer: get a conversion sheet out i dont know the exact measurments

step-by-step explanation: divide the number of feet with the nu,ber of milrs and there your answer

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
