Answer:
24 in
Explanation:
Using the right triangle formed by the height, radius and slant height
Applying Pythagoras' identity
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
h² + 7² = 25²
h² + 49 = 625 ( subtract 49 from both sides )
h² = 576 ( take the square root of both sides )
h = 24
