Answer:

181cm^2

Step-by-step explanation:

The minimum amount of paper needed to make the cup to the nearest whole number will be = to the surface area of the cylinder = A=2πrh+2πr2.

Where π= 22/7, r = 2.5cm, h = 9cm

A = 2×22/7×2.5×9+2×22/7×2.5×2.5

A= 141.428+39.285

A= 180.713

A = 181cm^2

Find the length of AB
AB²=20²+15²
AB²=400+225
AB²=625
AB=25

then find AD and BD
20²=AD·25
400=AD·25
AD=16
15²=BD·25
225=BD·25
BD=9
now use the geometric mean theorem (name?) to find CD
CD=√(9·16)
CD=√144
CD=12 cm

Zoey took 2.5 hours to bike the 60 kilometers from her house to the beach. It took her 3.5 hours to bike the same distance back
katrin2010 [14]

Answer:

The total distance Zoey biked = 120 kilometers.

Step-by-step explanation:

Given that Zoey took 2.5 hours to bike the 60 kilometers from her house to the beach.

Thus,

Distance covered from her house to the beach = 60 kilometers

Given Zoey took 3.5 hours to bike the same distance back to her house.

Thus,

Distance covered from beach to her house = 60 kilometers

Therefore, the total distance can be calculated by adding the distance covered from her house to the beach and the distance covered from the beach to her house.

Total distance = 60 + 60 = 120 kilometers.

Therefore, the total distance Zoey biked = 120 kilometers.
