Find the circumference of a circle whose<br>area is 49pi sq units.

sergij07 [2.7K]

Circumference of a Circle,C=2πr

π=3.14
r= of the circle

Area of the circle= πr²

We know that
Area= 49 π²

πr²=49

r²=49/π
=49/3.14
=15.60
r= √15.60
=3.9 units

Circumference of a Circle,C=2πr
=2*3.14*3.9
=24.492 units

A physical education teacher plans to divide the seventh graders at Wilson middle school into teams of equal size for a year-end

serg [7]

Answer:

• It is possible to divide the seventh graders into teams of equal sizes.

• 13 students should be on each team.

Explanation:

The seventh grade of Wilson consists of three classes; one with 28 students, one with 29, and one with 34. Therefore, the total number of students in seventh grade is:

$\text{Total}=28+29+34=91$

He wants each team to have between 4 and 8 students.

$\begin{gathered} \frac{91}{4}\approx22.75 \\ \frac{91}{5}\approx18.2 \\ \frac{91}{6}\approx15.2 \\ \frac{91}{7}\approx13 \\ \frac{91}{8}\approx11.4 \end{gathered}$

Therefore:

• It is possible to divide the seventh graders into teams of equal sizes.

• 13 students should be on each team.
