The area (A) of a circle with a radius of r is given by the formula A=3.14r^2 and its diameter (d) is given by d=2r. Arrange the

equations in the correct sequence to rewrite the formula for diameter in terms of the area of the circle.

Answer:

D=2\sqrt{\frac{A}{3.14}}

Step-by-step explanation:

we know that

The area of a circle is

A=3.14r^{2} ----> equation A

The diameter of a circle is

D=2r ----> equation B

Solve for r in the equation A

That means ---> isolate the variable r

Divide by 3.14 both sides

\frac{A}{3.14}=r^{2}

take the square root both sides

\sqrt{\frac{A}{3.14}}=r

Rewrite

r=\sqrt{\frac{A}{3.14}}

Substitute the value of r in the equation B

D=2\sqrt{\frac{A}{3.14}}

NO LINKS!! Find an nth-degree polynomial function with real coefficient satisfying the given conditions.
Sati [7]

n=3; We need a third degree polynomials with the following given zero's: 2 and 5i are zeros; f(-1)=156.

Since these are solutions

x = 2 ; x = 5i. Since imaginaries travel in pairs, the other answer is x= -5i.

We have (x-2)(x-5i)(x+5i) = 0

Now,

f(-1) = (-1-2)(-1-5i)(-1+5i) = 156.

f(-1) = (-3)(26) = -78.

But -78 x -2 = 156, so our polynomial becomes

Y= -2x (<em>x</em> - 2 ) x (<em>x </em>to the power of 2 + 25) = 0
