Answer:

4 inches

Step-by-step explanation:

The radius is the line from the center of the circle to the edge. We can assume the black line on the orange is the radius.

We want to find the diameter. The diameter is twice the radius, or

d=2r

We know the radius is 2, so we can substitute that in for r

d=2*2

Multiply

d=4

So, the diameter is 4 inches

Answer:

4 in is the diameter

Step-by-step explanation:

The radius is 2 in, it is half way across, and 2 radius is equal to one diameter.

The diameter is the entire way across the circle (crossing through the center point). In this case the diameter 4 in.

hope this helps :) pleas mark brainliest if you see fit :)

Write the equation of the line that passes through the points (-4,8) and (-2, -1).

IRINA_888 [86]

Answer:

y=-9/2x-10

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-1-8)/(-2-(-4))

m=-9/(-2+4)

m=-9/2

y-y1=m(x-x1)

y-8=-9/2(x-(-4))

y-8=-9/2(x+4)

y=-9/2x-36/2+8

y=-9/2x-18+8

y=-9/2x-10

A machine wheel spins at a rate of 500 revolutions per minute. If the wheel has a diameter of 80 centimeters, what is the angula

Setler [38]

The angular speed of the wheel is calculated as 52.36 radians per second

<h3>How to solve for the angular speed</h3>

The revolution of this wheel is said to be at 500 in a minute

This is also called the frequency of this wheel.

This can be written as

500rev in 60 seconds. 500/60 = 8.333 per second

Angular speed is given as

pi = 22/7

f = 8.333

Formular for angular speed = ω = 2*pi*f

w = 2 * 22/7 * 8.333

= 52.36 radians per second
