Question 780421
volume of a cylinder is pi r squared x height,

soo..

radius is 1/2 the diameter, so 1/2 of 5 is 2.5...... 2.5 x 2.5 is 6.25

3.14 x 6.25 x H = 125

combine like terms...

19.625 x H = 125

divide both sides by 19.625

h = 6.369426752

check your math   3.14 x 6.25 x 6.369426752 = 125
