Trick question: Jessica still only drank 3.5 glasses of water it doesn’t matter what her sister did it does not effect what Jessica drank.
Answer:
59.4 km
Step-by-step explanation:
First you need to find the circumference of the circle. 20*3.14=62.8. Then, you divide this by two, because there is only half of a circle, to get 31.4.
Then you can just add 16 + 12 + 31.4 to get 59.4.
The best answer to that question would be B) 4.02
