If the area of a circle measures 9π cm2, what is the circumference of the circle in terms of π?

8_murik_8 [283]

Answer: option B

Step-by-step explanation:

The circumference of a circle can be calculated with this formula:

$C=2\pi r$

Where "C" is the circumference of the circle and "r" is the radius of the circle.

The area of a circle can be calculated with:

$A=\pi r^2$

Where "r" is the radius.

Knowing the area, you can solve for the radius:

$r^2=\frac{9\pi cm^2}{\pi }\\\\r=\sqrt{\frac{9\pi cm^2}{\pi } }\\\\r=3cm$

Substituting into $C=2\pi r$ , you get that the circumference of this circle is:

$C=2\pi (3cm)=6\pi\ cm$

In the data set below, what are the lower quartile, the median, and the upper quartile? 626676848497 lower quartile = median = u

Dominik [7]

Answer:

Q1 = 4

Q2 = 7

Q3 = 42. 75

Step-by-step explanation:

Given the data:

626676848497

6, 2, 66, 7, 6, 8, 4, 8, 49, 7

Arrange in ascending order :

2, 4, 6, 6, 7, 7, 8, 8, 49, 66

The lower quartile (Q) :

1/4(n+1)th term

n = number of sample = 10

1/4(11)th term

2.75 term : (2 + 6) /2 = 8/2 = 4

Median :

1/2(n+1)th term

n = number of sample = 10

1/2(11)th term

5. 5 term : (7 + 7) /2 = 14/2 = 7

Upper quartile :

3/4(n+1)th term

3/4(11)th term

8.25 th term

3 /4 (8 + 49) = 42.75
