Question

write an algebraic expression that can be used to find the area of a triangle that has a base of 5 units and a height of x units.

Answer 1

v=1/3 x 3.14 x r^2 x H 
v=1/3 x 3.14 x 2.5^2 x H
v=1/3 x 3.14 x 6.25 x H
v=1/3 x 19.625 x H
1 x 19.625= 19.625   x   58.875  divide 58.875 by 3 = 19.625
                            1                3     
19.625 = Height
