Hello,
There is a mistake: it is 816 cm² !!! (an area)
length are multiplied by 2,
so area are mutiplied by 2²=4
Area B=816*4=3264 (cm²)
Answer:B
Step-by-step explanation:
This is something to memorize
y = r*sin(theta)
so if y = 2, then
2 = r*sin(theta)
Divide both sides by sin(theta) to get
r = 2/sin(theta)
r = 2csc(theta)
Y=2x+1... I hope this helps love! :)
