The radius of the circle is 2.86 cm.

Step-by-step explanation:

Given,

The circumference of the circle = 18 cm

To find the radius of the circle.

Formula

The circumference of a circle of radius r is 2πr

According to the problem,

2πr = 18

or, r = \frac{18X7}{22X2} = 2.86 (approx)

Hence,

The radius of the circle is 2.86 cm.

: Find the angle measures given the figure is a rhombus.
Marysya12 [62]

Answer:

74°

Step-by-step explanation:

A rhombus is a quadrilateral (has four sides). For a rhombus: opposite sides are equal, opposite angles are equal, all the sides are equal, the diagonals bisect each other, adjacent angles are supplementary, diagonals bisect the angles.

From the diagram below since adjacent angles of a rhombus are supplementary therefore:

32° + 2∠1 (diagonals bisect the angles) = 180

2∠1 = 180 - 32

2∠1 = 148

∠1 = 148 / 2

∠1 = 74°

Graph the equation using the point and the slope.
Alekssandra [29.7K]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have the equation of the line in point slope form

y-5=\frac{1}{5}(x-5)

where

the point is (5,5)

the slope is m=1/5

Remember that

The formula of slope is "rise over run", where the "rise" (means change in y, up or down) and the "run" (means change in x, left or right)

so

<em>To graph the line</em>

1. Plot the point (5,5).

2. From that point, count right 5 units and up 1 unit and plot a second point.

3. Draw a line through the two points

so

The new point is (5+5,5+1) ----> (10,6)

Plot the points (5,5) and (10,6) and draw a line through the two points

The graph in the attached figure
