The volume of a cylinder is found using the formula V = πr^2^h. Using π = 5, r = 10 and h = 10. Find the volume V.
Considering that the r and h are 10, you could still easily do it without calculator, even if the value of pi had plenty of decimals.
You guys are really overestimating the students this test was made for lol
