Caves are formed by the dissolution of limestone. Rainwater picks up carbon dioxide from the air and as it percolates through the soil, which turns into a weak acid. This slowly dissolves out the limestone along the joints, bedding planes and fractures, some of which become enlarged enough to form caves.
Answer :
⠀
Explanation :
We know,

Where,
- <em>r</em> is the radius of the cylinder. Here, the radius is 4 cm
- <em>h</em> is the height of the cylinder. Here, height is 6 cm
- Here, we will take the value of π as 3.14 approximately .
⠀
Substituting the values in the formula :
⠀

⠀

⠀

⠀

⠀
Therefore,
- The volume of the cylinder is 301.44 cm³ approximately.
Answer:
13.9%
Step-by-step explanation:
Given data
Expected weight = 230 pounds
Actual weight= 262 pounds
Required
The percent error
Error= Actaul- expected/ expected *100
Error= 262-230/230*100
Error=32/230*100
Error=0.139*100
Error=13.9%
Hence the error is 13.9%
