Answer:

ADB=45

Step-by-step explanation:

we know that angles a, b, c, and d are right, or 90 degrees. We also know that the two lines in the center are bisectors, which cut a angle perfectly in half. we can now use this equation for thet:

90/2=<ADB

ADB=45

How is the formula for the circumference of a circle derived? Drag and drop the correct word into each box to complete the expla

n200080 [17]

Answer:

diameter

circumference

$\pi$

diameter

Step-by-step explanation:

First, find the length of the diameter (d) and the length of the circumference of the circle (c).

Next, divide the length of the circumference c by the length of the diameter d and set up an equation

$\dfrac{c}{d}=\pi$

where the ratio equals to $\mathbf{\pi }$ (the definition of $\pi$ )

Then, solve the equation for the circumference c:

$c=\pi d$

Finally, substitute 2 times the radius for the diameter

$c=\pi \cdot 2r=2\pi r$
