Find the exact circumference of a circle with the given radius. 36 inches C = 72 in. 36 in. 18 in. IN PIE TERMS PLEASE!!!!!:)

katrin [286]

If the radius (r) is 36 inches, the circumference of the circle is C = 2pi r,
or C = 2pi(36 inches) = 72pi inches. Please note: that's pi, not pie.

PLEASE HURRY write the equation of the inverse function y=1/2cos^-1(pix)-3

GaryK [48]

Answer:

$f^{-1}(x) = \frac{cos(2x+6)}{\pi }$

Step-by-step explanation:

$y = \frac{1}{2} cos^{-1} (\pi x)-3$

Firstly, we've to interchange the variables.

$x = \frac{1}{2} cos^{-1}(\pi y)-3$

Solving for y

$x = \frac{cos^{-1} \pi y}{2} -3$

Adding 3 to both sides

$x+3 = \frac{cos^{-1}(\pi y)}{2}$

Multiplying 2 to both sides

$2(x+3) = cos^{-1} (\pi y)\\2x+6 = cos^{-1} (\pi y)$

Taking cosine on both sides

$\pi y = cos (2x+6)$

Dividing both sides by y

$y = \frac{cos(2x+6)}{\pi }$

Replace y by $f^{-1}(x)$

=> $f^{-1}(x) = \frac{cos(2x+6)}{\pi }$

Calculating area of rectangle

PSYCHO15rus [73]

Answer:

$Area = 216.108cm^2$ --- You

$Area = 216.940cm^2$ --- Another student

Reason: Because there is a variation in the given dimensions

Step-by-step explanation:

Given

Your measurement

$Length = 20.70cm; Width =10.44cm$

Another students'

$Length = 20.74cm; Width =10.46cm$

Solving (a): The area

Area is calculated as:

$Area = Length * Width$

For you

$Area = 20.70cm * 10.44cm$

$Area = 216.108cm^2$

For the other student

$Area = 20.74cm * 10.46cm$

$Area = 216.940cm^2$

Solving (b): Reason for the variation in the areas

The given measurements are estimates of the dimensions of the rectangle.

Since there is a variation in the estimates, there will be some level of variation in the calculated area.

Help me fast now thank

anastassius [24]

Answer:

3 cans

Step-by-step explanation:

area 1=.9×.3=.27 m²

area2=1/2×0.5×0.5=0.25/2=0.125 m²

total area=0.27+0.125=0.395 m²

area of 6 signs=0.395×6=2.370 m²

total cans reqd.=2.37/1=2.37

so 3 cans are reqd.
