Sin²t +cos²t =1

<span> x=2+3 sin t
sin t=(x-2)/3

</span><span>y=1-1/2cos t
y-1= - (cos t)/2 
cos t =-(y-1)/(1/2)

</span>(x-2)²/3² + (y-1)²/(1/2)² = 1

A circular piece of fabric has a radius of 1.2 ft. The fabric sells for $5.40 per ft². What is the total cost of the circular pi
Kisachek [45]
The answer is $24.41

Step 1. Calculate the area of the <span>circular piece of fabric.
Step 2. Multiply the area of the piece by the price of </span><span>$5.40 per ft² to get the total cost.

Step 1.
The area (A) of the circle with radius r is:
A = </span>π r²
π = 3.14
r = 1.2 ft

A = 3.14 * (1.2 ft)²
A = 3.14 * 1.44 ft²
A = 4.52 ft²

Step 2.
Make a proportion
1 ft² costs $5.40
4.52 ft² cost x

1 ft² : $5.40 = 4.52 ft² : x
x = 4.52 ft² * $5.40 / 1 ft²
x = $24.41
