30?
30pi = 2pi r
30pi / 2pi = 15
15 = r

Answer:

Step-by-step explanation:

The circumference formula for a circle is

C=2\pi r or C=\pi d

We'll use the second one since our problem wants us to find diameter.  If we know that the circumference is 30π, then we will sub in 30π for C and solve for d:

30π = πd so

30π/π = d

The π's cancel out, leaving us with a diameter of 30 inches.

Find the equation of the straight line which passes through each of the following pairs of points.
Tems11 [23]

Answer:

y = 3x + 1

Step-by-step explanation:

First, find slope:

y2 - y1 / x2 - x1

10 - 4/ 3 - 1 = 6 / 2 = 3

Then, put the equation into point-slope form using the point (1, 4):

y - y1 = m(x - x1)

where m is the slope

y - 4 = 3(x - 1)

If you want to put this into slope-intercept form, it would be

y-4=3(x-1)\\y - 4 = 3x - 3\\y = 3x + 1

A comparison of the measures of central angles and inscribed angles of circles to their intercepted arcs are listed in the table
geniusboy [140]

A central angle means an angle that is at the center of a circle and whose legs are intersecting the circle.

<h3>What is a central angle?</h3>

Your information is incomplete as the data is not given. Therefore, an overview will be given.

Central angles are shaped by an arc between the two points. When a central angle and the inscribed angle intercept the same arc, then the central angle would be the double of the inscribed angles while the inscribed angle will be half of the central angle.

The hypotenuse of a right triangle is 14 centimeters long. One of the legs of the triangle is 6 centimeters. What is the length
BartSMP [9]

Answer: 12.65 cm

Step-by-step explanation:

Use the Pythagoras theorem,

a^2 + b^2= c^2

You are given the hypotenuse , which is c and another leg which is either a or b, does not particularly matter- rearrange to find the missing length

c^2 - b^2 = a^2

14^2 - 6^2 = 160

Square root 160 to find the missing length

12.65

Hope this helped :)
