What is 19PI/12 use a half angle indentity to find each value.?

Well you really can't use a half angle identity unless you have a function in from of the angle.\n\n19pi/12 equals 285 degrees, just FYI.

A = pi * r^2\n\nIn this case r = c / 2pi = 8pi / 2pi = 4\n\nA = pi * (4)^2 = 16pi

Working above is good until this step:\n\n2 + 0.8x >0.9(x + 6)\n2 + 0.8x >0.9x + 5.4)\n0.1x > -3.4 ← Symbol error in this line\n\nShould read 0.1x < -3.4\nie x < -34

:)\nNice trick question.\nYou should mention that the whole 'equations' reads:\n2 times (pi) radians = 360 degrees (measuring angles).\ntherefore (pi) radians equales 180 degrees (half circle)\nBut the number (pi) is same old 3.14......

12.45 x 34.59 =\n1245/100 x 3459/100= \n(1245x3459)/ (100x100)=\n4306455/10000=\n430.6455

Use the double angle identities.

Divide each side by 12 to isolate the variable.\n12y/12=132/12\nYou end up with y=11.

join the 2 pointz frm da arc vit da radius.measure out da value of da angle forned here.then substitute da values 4 this formula:  2*pie*radius/da angle u measured\n\nhappy solvin!

divide all the numbers(except 1) less than the prime number and see if they come out as a full number\netc. 19 19/2=9R1  **/3=6R1   **/4=4R3  **/5=3R4  **/6=3R1  **/7=2R5  **/8=2R3  **/9=2R1 **/10=1R9  **/11-18=1R8-1

I get 8/pi as well.\ndivide up into cylinders each element 2pixsin(pix/2)dx integrate by parts gives:\n(-4cos(pix/2))+((8/pi)sin(pix/2))evaluated at 1 and zero.\nonly nonzero term is rhs at 1 which gives 8/pi.

Domain ~ x values\nRange ~ y values\n\nYou have to work the function and figure them out.

Area = πab where a and b are the semi-major and semi-minor axis length

simply subtract 7 from both sides. This leave you with\n\nx<_3

if y' = x/12\nthen\ny= x^2 /24\ns

his saying the area not the other side.\na= bh/2\nu know that this parallelogram is a rectangle and if u put adiagonal angle abc is a right. so u'll just use the formula\n12*13 over 2\n=78 units.
