Answer:
Step-by-step explanation: Fourteen can be expressed as 2 + 3 + 4 + 5, also a sum of consecutive positive integers. Some numbers can be expressed as a sum of consecutive positive integers in more than one way. For example, 25 is 12 + 13 and is also 3 + 4 + 5 + 6 + 7.
Well, let's do the math. The formula of a cylinder is 2 (pi, which will be estimated to 3.14) r h + 2 pi (radius times radius).
First of all, do 2 x pi, which is 6.28. Multiply 6.28 x 1.4 is 8.792. 8.792 x 5 = 43.96.
Now for 2 times 3.14 again, which is 6.28. But this time, we do 1.4 x 1.4, which is 1.96. With our new number, we do 6.28 x 1.96, which is 12.3088.
Add 43.96 + 12.3088, and you get 56.2988. You can round it to 56.3. So, the answer is 56.3 inches.

Step-by-step explanation:
Answer:
h = 17.65 m
Step-by-step explanation:
The given equation gives the speed at impact :
h is height form where the object is dropped
Put v = 18.6 m/s in the above equation.
So, the object must be dropped from a height of 17.65 m.
