Answer:

Volume = 18 * pi in^3 OR IF pi=3.14 THEN Volume = 56.52 in^3

Step-by-step explanation:

Volume = Area(circle) * Height

Volume = pi*(diameter/2)^2 *Height

Volume = pi* 2.25 * 8

Volume = 18 * pi in^3

And if pi=3.14 then:

Volume = 56.52 in^3

Answer:

V= 18 \pi

Step-by-step explanation:

V=πr²h

The radius is half of the diameter

so the radius is 3/2

r= 1.5 in

Now plug in

V= \pi 1.5²(8 in)

V= 18 \pi

Luda [366]

Number of customers = 300
Number of customers that are male and has an open-toe shoes = 11
P(male and open-toe) = 11/300

Number of customers that are male = 139 + 11 = 150
Number of customers that are male and has an open-toe shoes = 11
Given that the customer is male,
P(open-toe) = 11/150

No, the two probabilities are not the same. The first probability has 2 variables - the gender and the shoe-type. The second probability has only 1 variable - the shoe-type

Answer:

a) -2 degrees celsius

b) -5<-2

C) There would be an open dot on -2 and the line would go till the right end of the graph.

Step-by-step explanation:

a)-2 is warmer because -2 is a higher number than -5

b) -5 is less than -2

c) Every number above -2 on the graph is warmer than -2 so the line continues from -2 to then end.
