Answer:
The surface = pi*10cm2
Step-by-step explanation:
The area of any rectangle is Base * Height,
We know that the square originally has 10cm High, when is rolled to form a cylinder, it's new shape has a bottom side that is equals to a circle.
The length of a circle is 2*pi*Radio= pi*Diameter.
Since the square has the same length in each side, we know that pi*Diameter= 10cm*pi
The surface (area) of the cylinder is= Base * Height= 10cm*10cm*pi
Answer:
Distributive Property
Step-by-step explanation:

Answer:
The 4th answer, at the bottom.
Step-by-step explanation:
The first answer is proportional, because y is equivalent to .5x.
The second answer is also proportional, because the ratios are equivalent.
The third answer is also proportional, because the line goes through the origin.
The fourth answer isn't proportional, because the ratios aren't equivalent.
The average speed of his trip is = 12 mile/ hour
The total distance covered by the driver = 240 miles
The rate at which he traveled = 12 miles per hour
Therefore, the time he used to cover his distance
= 240/12
= 20 hrs
But average speed = distance/ time
= 240/ 20
= 12 miles/ hour
Therefore, the average speed of his trip is = 12 mile/ hour
