Using 70 points need your not spammers. to make an ice-cream cone, employees at an ice-cream shop completely fill the cone and then add one scoop of ice cream on top. the cone has a height of 6 inches and a diameter of 2 inches. to the nearest cubic inch, how much ice cream is in the cone before the scoop is added on the top? 6 in³ 19 in³ 25 in³ 75 in³

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

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
