Answers

Answer:

Step-by-step explanation:

Amy can invite 18 people (including herself). $200-$50=$150. $150÷8=18.75. You can't have 18.75 people so you round it down to 18. Hope this helps!

Step-by-step explanation: Take $200-$50=$150

now divide 150 by 8 which is 18.75 you obviously can't round up so you round down to just 18 and thats your answer. she can have 18 people there including herself

Find the lateral surface area of the cylinder. Round your answer to the nearest tenth.

i dont know lateral surface area lol

Answers

Answer:

72 pi

Step-by-step explanation:

Think of the lateral surface area as a label on a soup can. When you roll it out, then the circumference becomes the length and the height of the cylinder becomes the width or vise versa. So if 2(pi)(r) is the formula for the circumference, then that is 8. 8*9 is 72 and you multiply that by pi to get 72 pi

Can you only find the exact number of a square root by calculator? If there are any other ways can you give me the name of the process and how to do it.

Answers

you can multiply the number by itself that’s what it means

looking at the factors of the number is the only other way i can think of. for example, if you’re looking for the square root of 49, the factors would be 1,49,and 7 and 7. 7 times 7 is 49, therefore the square root of 49 is 7. It gets a little more difficult for bigger numbers though.
