The area (A) of a circle with a radius of r is given by the formula and its diameter (d) is given by . Arrange the equations in

ella [17]

Answer:

see explanation

Step-by-step explanation:

A = πr² ← r is the radius and r = $\frac{1}{2}$ d ← d is the diameter

Hence

π ( $\frac{1}{2}$ d)² = A, that is

$\frac{d^2\pi }{4}$ = A ( multiply both sides by 4 )

d²π = 4A ( divide both sides by π )

d² = $\frac{4A}{\pi }$ ( take the square root of both sides )

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

This question please

AlexFokin [52]

19^2 + x^2 = 21^2

19^2 = 361

21^2= 441

361 + x^2 = 441

x^2 = 441-361 = 80

x = sqrt(80) = 8.944 round to nearest tenth = 8.9

Flor and Mo both donated money to the same charity. Flor gave three times as much as Mo. Between the two of them, they donated $

BlackZzzverrR [31]

To answer this question, you would divide the total by 3 to find the money that Mo gave. so 280/3= $93.33. I would check my math, just to be safe, however, I hope this helps you out.
