Answer:
19.72 cm²
Step-by-step explanation:
A solid circular cylinder has a base radius 5 cm and a height 12.5 cm.
The volume of cylinder is given by :
When r = 5.05, new volum becomes,
Increase in area = 1000.97 - 981.25 = 19.72 cm²
So, the increase in surface area of the cylinder is equal to 19.72 cm².
Since I do not have answer choices, I can conclude things that may or may not be an answer choice. Just from the problem, you can tell that Marie lost more weight, because 175 -150 = 25, while 190 - 180 = 10. Indirectly, you can say that she might have worked out more, or changed her diet, although that would merely be an inference. If you have answer choices please let me know and I can answer more. Hope this helps. Please rate, leave a thanks, and mark a brainliest answer (Not necessarily mine).
Answer: 8 short response questions and 12 multiple choice questions
Step-by-step explanation:
Let m represent multiple choice questions
Let s represent short response questions
m + s = 20 --> Amount of questions
3 m + 8 s = 100 --> Total number of points for each question
Solve using elimination, multiply the first equation by -3
-3m-3s=-60
3 m + 8 s = 100
----------------------
5s=40
s=8
m+8=20
m=20-8
m=12
Therefore, there are 8 short response questions and 12 multiple choice questions
