Question:

Find a volume of a cylinder:

Solution:

Remember that the volume of the cylinder with radius r and height h is given by the following formula:


V\text{ = }\pi r^2h

then, replacing the data of the problem into the previous equation, we get:


V\text{ = }\pi(4^2)(10)\text{ = 3.14 (16)(10) = 502.4}

thus, we can conclude that the correct answer is:


V\text{ = 502.4}
