V = 1/3* h * r^3 pi
V ' = 1/3* h/3* (2r)^3 pi = h/9 * 8r^3 * pi

V ' / V = (h/9 * 8r^3 * pi) ÷ ( 1/3* h * r^3 pi ) = (8 * 3)/ 9 = 8 /3

hichkok12 [17]

Answer:

0.3745

Step-by-step explanation:

Data

mean ( $\mu$ ): 80

standard deviation ( $\sigma$ ): 4

Normal distribution table is in figure attached .

$Z = \frac{x - \mu}{\sigma
}$

Z = (85 - 80)/4 = 1.25

Area below curve = 0.3944

Z = (82 - 80)/4 = 0.5

Area below curve = 0.0199

Proportion of exam scores between 82 and 85?

0.3944 - 0.0199 = 0.3745
