3. Daniela is putting lace trim AROUND the border of a circular tablecloth. The tablecloth has a diameter of 1.2
meters. To the nearest meter, what is the least amount of lace she needs? (hint: think about around, is that
area or circumference? Also, think about rounding UP because she will need more than enough to cover the
table)
a. 3m
B. 4m. C 7m D 8m

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

i would be 2,000 just get the square root of 50 which is 2500 and the divid 4/5 and last thing multiply the answer you get for that by the square root of 50
