Acylinder has a base area of 20.7 in2 and a lateral area of 25.3 in2. what is the surface area of the cylinder? use 3.14 for π and round to the nearest tenth, if needed.

To solve this problem you must apply the proccedure shown below:

1. You must apply the following formula for calculate the surface area of a cylinder:

Where is the lateral area and is the area of the base.

2. Therefore, when you substitute values into the formula, you obtain:

The answer is:

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%
