If you know the diameter of a circle,

arsen [322]

Step-by-step explanation:

a. Area of a circle = πr², where r means radius.

Step 1: converted diameter to radius.

diameter = 2 radius

In other way of writing, radius = $\frac{1}{2}$ diameter.

Step 2: substitute radius into the formula.

Area of a circle = π( $\frac{1}{2}$ d)²

Step 3: substitute π into the formula.

some question is given the value of π), if not substitute 3.14 for π.

Area of a circle = 3.14( $\frac{1}{2}$ d)²

Step 4: substitute d into the formula, then we can solve its area.

b. a. Circumference of a circle = 2πr, where r means radius.

Step 1: converted diameter to radius.

diameter = 2 radius

In other way of writing, radius = $\frac{1}{2}$ diameter.

Step 2: substitute radius into the formula.

C = 2π( $\frac{1}{2}$ d)

Step 3: substitute π into the formula.

some question is given the value of π), if not substitute 3.14 for π.

C = 2(3.14)( $\frac{1}{2}$ d)

Step 4: substitute d into the formula, then we can solve its circumference.

What is the distance from Cto D?

IRINA_888 [86]

Given:

The two points C(2,-1) and D(5,3) on a coordinate plane.

To find:

The distance from C to D.

Solution:

The distance between two points is defined by the distance formula.

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

The two points are C(2,-1) and D(5,3). Using the distance formula, we get

$CD=\sqrt{(5-2)^2+(3-(-1))^2}$

$CD=\sqrt{(3)^2+(3+1)^2}$

$CD=\sqrt{(3)^2+4^2}$

On further simplification, we get

$CD=\sqrt{9+16}$

$CD=\sqrt{25}$

$CD=5$

The distance from point C to D is 5 units. Therefore, the correct option is A.

Q = {1.7, 1.1, 1.4, 2.1, 2.3, s}. What is the absolute difference between the greatest and least possible values of the median o

Daniel [21]

Answer:

Absolute difference between the medians = 0.35

Step-by-step explanation:

After arranging Q in ascending order excluding s, we get

Q = {1.1, 1.4, 1.7, 2.1, 2.3}

Here, the median is 1.7 ( The middlemost value is the required median.)

Now, if s < 1.7,

Q= {1.1, s, 1.4, 1.7, 2.1, 2.3}

Now for the least value, median = 1.55

If s > 1.7,

Q = {1.1, 1.4, 1.7, 2.1, s, 2.3}

Now for the greatest value, median = 1.9

Absolute difference between the medians = |1.9 -1.55|

= 0.35
