$A= \pi r^2 \ \ \ and \ \ \ C=2 \pi r \ \ \ \ \to \\ \\ \cfrac{\pi r^2 }{2 \pi r}= \cfrac{22}{1} \ \ \ \ \to \ \ \ \ \ \cfrac{ r }{ 2}= \cfrac{22}{1} \ \ \ \ \to \ \ \ \ \ r=22*2=44 \ cm \\ \\ \\ C=2 \pi r=2*3.14*44=276.32 \ cm$

Answer is 276.32 cm

The mean length of the sides of a triangular plot of land is 18 yards.

The mean is all of them added together divided by the number, so multiple the mean by the number of sides, 3, and that's the perimeter. 18 x 3 = 54

How do i prove 2sec^2x-2sec^2xsin^2-sin^2x-cos^2x=1

kramer

$2\sec^2x-2\sec^2x\sin^2x-\sin^2x-\cos^2x=2\sec^2x(1-\sin^2x)-(\sin^2x+\cos^2x)$

Since $\sin^2x+\cos^2x=1$ , you have

$2\sec^2x(1-\sin^2x)-(\sin^2x+\cos^2x)=2\sec^2x\cos^2x-1$

and since $\sec x=\dfrac1{\cos x}$ , you end up with $2-1=1$ .

Can someone explain to me how to do this

Otrada [13]

Angles on a straight line add up to 180°, so:

x + 60 = 180

x = 180 - 60

x = 120°
