Answer:

Area

1/2

Radius

Step-by-step explanation:

We know that for any circle with radius r the formula for the area and circumference of the circle is given as:

Area of circle=πr².

and circumference of circle = 2πr.

Hence, to describe the relationship between the area of a circle and its circumference.

The Area of circle is 1/2 times the radius times the circumference.

( Since,

Area=1/2 × r× 2πr

Area=πr² )

If \left| OA\right| =5∣OA∣=5 and \left| OA'\right| =7.5∣OA ′ ∣=7.5, what is the scale factor, rr, of this dilation?

Igoryamba

Answer:

The scale factor is 1.5

Step-by-step explanation:

Given

$\left| OA\right| =5$

$\left| OA'\right| =7.5$

Required

Determine the scale factor

The scale factor (k) is calculated using:

$k = \frac{\left| OA'\right|}{\left| OA\right|}$

Substitute values for OA and OA'

$k = \frac{7.5}{5}$

$k = 1.5$

<em>The scale factor is 1.5</em>

Solve the simultaneous equations y=3x+2 and y=x+6

kogti [31]

Answer:

x=2

Step-by-step explanation:

y=3x+2

y=x+6

Since you're stating that, they both equal because equation is equated to equation 2 because of the Y.

Therefore, substitute into both equations as shown:

3x+2=x+6

3x-x=6-2 (bring 2 to the other side by subtracting 2 as well as x)

2x=4

2x/2=4/2 (dividing 2 on both sides to get rid off 2 in 2x)

x=2.
