1. cone, 1 vertex
2. sphere, nothing
3. pentagonal prism?
wait but can't every face be a base???

Answer:
1-6 you need to write the JHI DEF where the radius center point is in the middle of each shape next to 1-6 some have 2 shapes so use 6 letters there.
Step-by-step explanation:
1. Area = 72 of 360 = 20% of 716.3 = 143.26inch*2 =JHI
2.Area = 19 of 360 = 68.4% of 69.4 = 47.46km^2 =DEF
3. Area = 92 of 360 = 25.56% of 153.9 = 39.33cm^2
4. Area = 226 of 360 = 64.57% of 706.9 = 456.45ft^2
5. Area = 74 of 360 = 20.55% of 153.9 =31.63 inch^2
6. Area = 326 of 360 = 90.56% of 1452 -137.07 = 1314.93m^2
A.; 14 doesn’t work and neither does 8 or 3.
Answer:
x=1.75 hour
Step-by-step explanation:
200km=2.5
140km=x
2.5 * 140=200x
350=200x
x=350/200
x=1.75
the time it will take is x=1.75 hour
