hello :
<span>(-101)+102+(-103)+104+...+(-199)+200
=( </span>(-101)+(-103) +....+ (-199) ) +( (102) + ( 104) +....+(200))
let : A = ( (-101)+(-103) +....+ (-199) )
B = ( (102) + ( 104) +....+(200))
note : the sum n term of arithemtic sequence
S= n/2(u1 + un)
un = u1 +(n-1) d u1 : the first term d : the common diference
in A : u1= -101 d = -2 n = 49...
in B : u1 =102 d=2 n= 49
A = 49/2(-101-199) =-7350
B=49/2(102+200)=4949
(-101)+102+(-103)+104+...+(-199)+200 = A+B =-2401
A) to work out area of a circular pan you use 3.14 x R^2 so the area would be 3.14x(6)^2, which gives us 113.04in^2. The rectangular pan has area 8x11 which is 88in^2.
B) to work out volume you multiple the areas by the depth. So the circular one is 226.09in^3 and the rectangular one is 176in^3.
C) this means that the circular pan has a larger volume
Hope this helped and sorry if anything is wrong :)
99.7% encompasses about 3 standard deviations either side of the mean.
82 ±3*2 = (76, 88)
About 99.7% of the values lie between 76 and 88.
720, 1440, 2880 these are the next three numbers
