What is the slope of the line that passes

Snowcat [4.5K]

Answer:the answer is 5/2 because if yo subtract y2 from y1 and x2 from y2 thats the answer you get.

But you might not get that answer straight away you need to simplify the initial value and keep going until you cant simplify without a remainder.

A = 1 4 π d 2 what is the formula to calculate the diameter of a circle

Anestetic [448]

Answer:

$D=2\sqrt{\frac{A}{\pi}}$

Step-by-step explanation:

we know that

The area of the circle is equal to

$A=\frac{1}{4}\pi D^{2}$

where

D is the diameter of the circle

Solve for D

That means-----> Isolate the variable D

Multiply both sides by 4 to remove the fraction

$4A=\pi D^{2}$

Divide both sides by π

$\frac{4A}{\pi}=D^2$

square root both sides

$\sqrt{\frac{4A}{\pi}}=D$

Rewrite

$D=\sqrt{\frac{4A}{\pi}}$

Simplify

$D=2\sqrt{\frac{A}{\pi}}$
