Formula for volume of cylinder is area of base time height
area of base equal pir^2 =3,14*(2,5)^2 = 3,14 *6,25 = 19,625 inches squared
V=area time height
170 = 19,625 *h
h = 170/19,625 = 8,662 inches
X² - √3x -x +√3
x(x-√3) -(x-√3)
(x-√3)(x-1)
zeroes are x-√3 = 0
x = √3
and x-1 =0
x =1
z=(63-84)/3= -21/7= -3
P(x>63)=p(z > -3) = .9987 or 99.87%
Those two numbers are 30 and 12.
30+12=42
and
30*12=360
:P
(32°) = 1700 feet / x => x = 1700 feet / tan(32°) = 1700 feet / 0.625 = 2720 feet.
