1. The formula for the area of a triangle is : A = 1/2bh
Insert the values in to the formula and you get : A = 1/2(4)(16)
Solve : A = 1/2(64)
A = 32
2. Formula for area of triangle : A = 1/2bh
Insert value into formula : 38 = 1/2(12)h
I solved this one by dividing 38 by 12 (do this to get 3.167 = 1/2h) and then multiplying by 2 (do this so you get 6.33 = h)
h = 6.33
3. Find sides of the square by finding the square root of the area : √244 = 15.62 (because 244 is not a perfect square, the answer is not going to be perfect)
Because you know that each side of the square is about 15.62 cm tall, you can say that the cylinder is also 15.62cm tall.
I hope this helps. Let me know if the answer was correct and/or you need anymore help. :)
