The circumference of a circle has the formula: 2*pi*r. So, we could easily determine the value of r.

C = 2*pi*r
12*pi = 2*pi*r
12 = 2r
r = 12/2
r = 6 inches

Knowing the r, we could find the area which has the formula

A = pi*r^2
A = pi*6^2
A = 113.1 square inches

Hope this helps!

On a multiple choice test with 17 questions, each question has four possible answers, one of which is correct. For students who
Ira Lisetskai [31]
<h2>The required "option c) 4.3" is correct.</h2>

Step-by-step explanation:

Given,

Total number of multiple choice questions = 17

To find, the mean for the number of correct answers = ?

Each question has four possible answers.

If guessing at random:

There is only one in four chances.

\dfrac{1}{4}\times 100 =  25 % chance of getting a particular question right.

This is the same probability for each of the 17 questions.

If there is a 25 % chance of getting any given question right.

There are 17 questions.

∴ The total number of questions you will expect to get right =

25 %  × 17

= \dfrac{25}{100} \times 17

= \dfrac{17}{4}

= 4.25

≈ 4.3

∴ The mean for the number of correct answers = 4.3

Thus, the required "option c) 4.3" is correct.
