Find the diamter of a circle if its area is 706.9mm²​
Masteriza [31]

Answer:

<h2>30 mm</h2>

Step-by-step explanation:

The formula of an area of a circle:

A=\pi r^2

<em>r</em><em> - radius</em>

<em />

We have

A=706.9\ mm^2

Substitute:

\pi r^2=706.9          <em>divide both sides by π</em>

r^2=\dfrac{706.9}{\pi}        <em>use π ≈ 3.14</em>

r^2\approx\dfrac{706.9}{3.14}\\\\r^2\approx225\to r=\sqrt{225}\\\\r= 15\ mm

The diameter <em>d = 2r</em>.

Therefore

d=2(15)=30\ mm

Simplify (sinx + cosx) ^2/ sin2x
Aleksandr [31]

\csc 2x+1

Step-by-step explanation:

  • \frac{(\sin x+\cos x)^2}{\sin2x}

  • We expand (\sin x+\cos x)^2 using algebraic identity (a+b)^2=a^2+b^2+2ab

  • =\frac{\sin^2x+\cos^2x+2\sin x.\cos x}{\sin2x}

  • = \frac{1+\sin2x}{\sin2x}

  • =\frac{1}{\sin2x}+\frac{\sin2x}{\sin2x}

  • =\csc 2x+1
