Find radius (using distance formula ) between the two points then circumference = 2 * radius * pi
Use law of cosines
BC^2 = AB^2 + CA^2 - 2 (AB)(CA) cos A solve for cos A
Each 'hour' position is 30 degrees (12 hours in full circle 360)
Two less hours in the hand position would be 60 degrees difference...
NO is 5 out of (5+2+1) = 5/8ths of 24 5/8 * 24 = 15 units
That is what I get too....I counted the wrong direction from 200....I should have counted UP.....after I saw your answer, I re-counted and got 218 also
Thanx! Alan ~EP
Possible number 5 * 4 * 3 * 2 * 1 = 120 numbers
3/5 ths end in an odd number making the number an odd number 3/5 * 120 = ______
convert 2 inches to feet 2/12 = 1/6 ft then radius = 1/12 ft
Area * length = volume
pi (1/12)^2 *100 = pi 100/144 = 25/36 pi ft3 =~~ 2 ft3 ( to nearest ft3 )
Educated guess: 179
Area sequence pi (64 + 16 +4 + 1) the common ratio is 1/4 as you can see
sum of an infinite sequence
S = a1 / (1-r)
64 pi / (1 - 1/4 ) = 85.33 pi in2
