You simply need to find the volume of the drum.(volume of cylinder)

v= pi r^2 h

pi=3.14

r=1.2

h=4ft×$22=$88

therefore:

3.14×1.2^2×88
=3.14×2.4×88
=7.526×88
=$662.288
=$662.3

Write a number in which the value of the 3 is ten times greater than the value of the 3 in 135, 864
Aleonysh [2.5K]

Answer:

345,456

Step-by-step explanation:

The value of 3 in 135,864 is 30,000.

We want to write a number that is ten times 30,000.

We could write any other number in which the value of 3 is 300,000.

There are infinitely many numbers that we can write.

Some examples are:

345,456

1,315,445

5,354,456

and so on and so forth.

1. A certain manufacturing process to build phone batteries results in the production of defective batteries at a rate of 5% (0.
lesya [120]

Answer:

0.5 ; 0.475 ; 0.689 ; 0.4013

Step-by-step explanation:

Given that:

Rate of production of defective batteries p = 0.05

Number of batteries produced (n) = 10

The expected number of defective batteries = mean = n * p = 10 * 0.05 = 0.5 batteries

Variance of defective batteries :

Var(X) = n * p * q ; q = 1 - p

Hence,

Var(X) = 10 * 0.05 * 0.95 = 0.475

Standard deviation (X) = sqrt(variance) = sqrt(0.475) = 0.689

Probability that atleast 1 battery is defective :

Using the binomial probability function

P(x ≥ 1) = 1 - p(x = 0)

= 1 - q^n

= 1 - 0.95^10

= 1 - 0.59873693923837890625

= 0.40126306076162109375

= 0.4013

Which solid has a greater volume
tiny-mole [99]

Answer:

C.  They are equal

Step-by-step explanation:

The volume of a cone is

V = (1/3)πr²h       where r is the radius, and h is the height.  

The volume of this cone is...

V = (1/3)π(5²)(9)

        V = (1/3)π(25)(9)

             V = (225/3)π

                  V = 75π

The volume of a cylinder is

V = πr²h      where r is the radius and h is the height

The volume of this cylinder is

V = π(1²)(75)

   V = 75π
