                  Find the circumference of the circle and show work. [refer to  

                  attachment]

\large\blue\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}

          Formula for Circumference of a Circle:-

        \dashrightarrow\star\bigstar\boxed{\boxed{C=2\pi r}}}

Where

  • C = circumference
  • π = pi (3.14…)
  • r = radius, which in this case is equal to 8

Substitute the value of r and solve:-

         C=2π(8)

        On simplification,

     

C=16π

On further simplification,

C=50.3

Therefore, we conclude that the circumference of this circle is

\dashrightarrow\star\bigstar\boxed{\boxed{\underline{\bold{C=50.3\:yd}}}}\bigstar\star\dashleftarrow

<h3>Good luck.</h3>

In a recent semester at a local university, 540 students enrolled in both General Chemistry and Calculus I. Of these students, 5
Law Incorporation [45]

Answer:

0.9056

Step-by-step explanation:

We are given;

Number of students enrolled in both General Chemistry and Calculus I = 540 students

Number of students who received an A in general chemistry = 51 students

Number of students who received an A in calculus = 59 students

Number of students who received an A in both general chemistry and calculus = 30 students

Now, we want to find the probability that a randomly chosen student did not receive an A in general chemistry.

So, first of all let's calculate number of students who didn't receive an A in chemistry.

So,

No without A in chemistry = 540 - 51 = 489 students

So, probability that a randomly chosen student did not receive an A in general chemistry = 489/540 = 0.9056
