We will need calculate the area of the top, the base and sides.
area of the top=πr²
area of the base=πr²
area of the side: 2πrh
surface area of a cylinder: area of the top + area of the base +area of the side
surface area of a cylinder=πr²+πr²+2πrh=2πr²+2πrh=2πr(r+h)
Data:
r=radius=diameter / 2=4 yd /2=2 yd
h=heigth=12 yd
Surface area of this cylinder=2π(2 yd)(2 yd + 12 yd)=4π yd(14 yd)=56π yd².
Answer: the surface area of this cylinder is 56π yd².
She had left a 18% tip because you multiply the cost by the tip percentage 12.5*0.18=2.25 after that you add the values together 12.50+2.25=14.75.
Answer:
b
Step-by-step explanation:
null hypothesis will be book sales are related to bakery sales.
We reject null hypothesis if we do not have statistical evidence that there is significant relationship between book sales and bakery sales.
Answer:
B. 1 :)
Step-by-step explanation:
Every time the x value gets bigger, the y laue does too. Positive numbers are larger than negative ones so every time we get closer to 0, our values get bigger :)
