The circumference of a circle is 11pi ft. find its diameter, in feet​

Mathematics
1 answer:
mixer [17]3 years ago
3 0

Answer:

The diameter would be 11 feet

Step-by-step explanation:

C = pi * d

we don't know D so we rearrange the equation to solve for D by dividing both sides by pi:

C/pi = d

Now we plug in everything

11pi/pi = d

The pi cancel each other out leaving with 11 feet

Therefore D = 11 feet

The length of an arc of a circle is 7.34 units, and the measure of the corresponding central angle is 81°. What is the approxima
Olin [163]

The radius of the circle is 5.2 units if the length of an arc of a circle is 7.34 units, and the measure of the corresponding central angle is 81°

<h3>What is a circle?</h3>

It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

We have:

Length of the arc of a circle:

s = 7.34 units

The measure of central angle:

θ = 81 degrees =  1.413 radians

s = rθ

r is the radius of the circle

7.34 = r(1.413)

r = 5.19 ≈ 5.2 units

Thus, the radius of the circle is 5.2 units if the length of an arc of a circle is 7.34 units, and the measure of the corresponding central angle is 81°

Ramona has a new job as a chef. She earns the same
DaniilM [7]

Answer:

y = 10x  + 100

Step-by-step explanation:

Given the information:

She earns the same  amount per hour as she did in her old job $ 100 sign-on bonus

=> the equation for line p in the form y= mx  where:

  • x is the number of hour she worked
  • y the money she earned

=>  the equation for line q in the form y= mx + 100 ($ 100 sign-on bonus )

From that, we see that the two equations have the same slope or you can use a transformation to map line p onto line q

We can create two points (0, 0) and (2, 20) are on line p  

<=> m = \frac{y2-y1}{x2-x1} = \frac{20-0}{2-0} = 10

The equation for line p is y = 10x

=>The equation for line q should include the hourly earnings at the

new job plus the sign-on bonus. The equation is y = 10x  + 100

Hope it will find you well.
