What is the volume of a right circular cylinder with a radius of 5cm and a height of 12cm?

Tom [10]

Answer: $V=942.47cm^{3}$

Step-by-step explanation:

1. To solve this problem you must use the following formula for calculate the volume of a right circular cylinder, which is shown below:

$V=\pi*r^{2}*h$

Where r is the radius and h is the height.

2. Now, you must substitute the values given in the problem. Therefore, you obtain the following result:

$V=\pi*(5cm)^{2}*(12cm)$

$V=942.47cm^{3}$

Step-by-step explanation:

Given the expressions :

Q(18)

Q(30) = 27.5

Function Q gives a puppy's weight in pounds as function of its age in months

What does each expression represent in this situation?

A function is generally represented in the form a(x) ;

Hence, Q(18) is a mathematical representation of the weight in pounds of a puppy after 17 months

Q(30) = 27.5 ; This means that the weight of puppy after 30 months will be 27.5 pounds. 27.5 is the result of working out the function Q at 30.

A television network is about to telecast a new television show. Before a show is launched, the network airs a pilot episode and

Basile [38]

Answer:

(E) 0.83

Step-by-step explanation:

We will solve it using conditional probability.

Let A be the event that a TV show is successful.

P(A) = 0.5

A' be event that the show is unsuccessful

P(A') =0.5

Let B be the event that the response was favorable

P(B) = 0.6

Let B' be the event that the response was unfavorable/

P(B') = 0.4

P(A∩B) = 0.5 and P(A∩B') = 0.3

We need to find new show will be successful if it receives a favorable response.

P(A/B) = $\frac{P(A∩B)}{P(B)}$

= 0.5/0.6

= 0.833
