D. 35, since that would be the longest amount. of time walking away from her house, she should be the farthest amount of feet away from her house
It would be 60 because all you do is double the radius because it is only half of the circle
For this you have to get r by itself so you put 1 over 3 and move it to the other side and then you get 2/3 as an answer
Okay well I do it like this. 3+8=11. I put a 1 down and carry the other. so I do 7+0+1=8 so now I have 81, and last I do 6+3=9. so the answer would be 981.
Have a nice day!
