Answer:
D: 768
Step-by-step explanation:
First, he divides a piece of paper in half.
He gets two pieces.
Next, he cuts each of the pieces into three parts.
Thirdly, he cuts each of the 6 pieces into 8 pieces.
Lastly, he divides each piece into 16 parts.
He has 768 pieces in the end. (D)
What we know:
shape is circular
Area=64π yr²
Area=πr²
circumference=2πr
In order to find circumference we need r=radius. We can use the area to find r by solving for r using substitution of the information we know above.
Area=πr²
64π=πr² substitution
64π/π=π/πr² multiplicative inverse
64=r²
√64=√r² properties of radicals
8=r We would get two solutions, a positive and negative one but we will only use the positive solution since radius is positive
Circumference=2πr
C=2π(8)=16π yards
Your rise is 5 and your run is 3, your y-intercept is 0, therefore y=(5/3)x
Sorry hun I’ve never learned that
