The area of the circle is 3.14 square millimeters

<h3>Calculating Area</h3>

From the question, we are to the area of the circle

The area of a circle can be determined by using the formula,

A = πr²

Where A is the area of the circle

and r is the radius of the circle

From the given information,

r = 1 mm

and π = 3.14

Putting the parameters into the equation, we get

A = 3.14 × 1²

A = 3.14 × 1

A = 3.14 mm²

Hence, the area of the circle is 3.14 square millimeters

A rectangle has a width of 5 yd and a length of 9 yd.
Yuri [45]

Answer:

Option The area is increased by a factor of 16

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its areas is equal to scale factor squared

Let

z-----> the scale factor

x------> the area of the dilated rectangle

y------> the area of the original rectangle

z^{2}=\frac{x}{y}

we have

z=4 ------> is an enlargement

so

substitute

4^{2}=\frac{x}{y}

16=\frac{x}{y}

x=16y

therefore

The area is increased by a factor of 16

nalin [4]

Answer:

a) 19 students

b) the mean 3 9/19

the median 3

the mode 3

c) the range 6

Step-by-step explanation:

The data set shows that

0 points gets 1 student,

1 point gets 1 student,

2 points get 2 students,

3 points get 6 students,

4 points get 4 students,

5 points get 3 students and

6 points get 2 students.

a) There are 1+1+2+6+4+3+2=19 students.

b) The mean is

\dfrac{1\cdot 0+1\cdot 1+2\cdot 2+6\cdot 3+4\cdot 4+3\cdot 5+2\cdot 6}{19}=\dfrac{66}{19}=3\dfrac{9}{19}.

The average score is 3 9/19 points.

The median is 10th term in the data set - 3 points (means the middle score in the data set)

The mode is 3 points (means most happened score)

c) The range of the data is 6-0=6 points.
