Answer:

192.92 ft^3

Step-by-step explanation:

volume of a cone = \frac{1}{3}πr²h

π = 3.14

r = radius ]

h = height

the base of a cone is in the shape of a circle. thus, the circumference of the base is equal to the circumference of a circle

circumference of a circle= 2πr

30.144 = 2 x 3.14 x r

r = 30.144 / 6.28

r = 4.8

Volume = 1/3 x 3.14 x 4.8² x 8 = 192.92 ft^3

PLZ HELP ME I NEED THIS ASAP
Andru [333]

Mean = 110

Sample size = 45

Standard deviation = 6

Z score for 90% is 1.645 ( from Z-table).

Lower Limit = Mean - Z(SD/√Sample size))

Lower limit = 110 - 1.645(6/√45)

Lower limit = 108.5

Upper Limit = Mean + Z(SD/√Sample size))

Lower limit = 110 +1.645(6/√45)

Lower limit = 111.5

The interval is (108.5, 111.5)

If sin t = -8/17 and t is a quadrant III angle, find cot t
nirvana33 [79]

Answer:cot t = 1.875

sin t=\frac{-8}{17} but sin²t + cos²t = 1 ⇔ cos²t = 1 - sin²t

⇔cos t = \sqrt{1-sin^{2}t }=\sqrt{1-(\frac{-8}{17})^{2}  }=|\frac{15}{17}|

but  t is a quadrant III angle => cos t = \frac{-15}{17}

=> cot t = \frac{-15}{17}:\frac{-8}{17}=\frac{15}{8}=1.875
