Final answer:
The volume of the cylinder is calculated using the formula V = πr²h. After substituting the given values and performing the multiplication, the cylinder's volume, rounded to one decimal place, is 3178.1 cm³.
Step-by-step explanation:
The subject of this question is a mathematical problem about geometric solid volumes—in this case, a cylinder.
To calculate the volume of a cylinder, you use the formula V = πr²h where V is volume, r is radius, h is the height, and π (Pi) is a constant approximated as 3.14.
In this situation, the radius (r) is 12cm, the height (h) is 7cm. Therefore, plugging these values into the formula gives V = π*(12cm)²*7cm = 3.14*144cm²*7cm = 3,178.08cm³. But the question has asked you to give the answer rounded to 1 decimal place (DP), so the final volume is 3,178.1 cm³.
