Answer:

d = 24

Step-by-step explanation:

The area of a circle is given by A = π * r²

We are told the area of the clock is 144π.

Let's clear the formula for the radius:

r² = A / π

r² = 144π / π

r² = 144

r = √144

r = 12

The diameter is two times the radius, d = 2r = 2*12 = 24.

if y varies inversely with x and the constant of variation is 4.5 what are the values missing in the table
Alexxandr [17]
Seems like you forgot to attach the table.
For this reason, I will explain how to solve this question and you can apply using the numbers in your table.

We are given that:
y is inversely proportion to x. This means that as y decreases, x increases and vice versa.
Writing this into equation, we would get:
y = c/x where c is the constant of proportionality.
Now, we have the constant of proportionality given as 4.5.
This means that the equation that relates x and y is:
y = (4.5) / x

So, to fill in the table, we would substitute with the given x or y in the equation above and solve for the other variable.

Examples:
If given that x=2, then:
y = (4.5) / (2) = 2.25
If given that y=3, then:
3 = (4.5) / x
x = (4.5) / (3) = 1.5

Hope this helps :)

I hope someone can help me here please don't answer nonsense!​
Karolina [17]

Answer:

30 degrees

Step-by-step explanation:

Angle B is an inscribed angle -- its vertex is on the circle and it intersects the circle in two points, <em>A</em> and <em>C</em>.

The measure of an inscribed angle is always one half the measure of the intercepted arc.  The intercepted arc has measure 60 degrees, so the measure of angle B is 30 degrees.
