Answer : False

Consider a right circular cone, with height = h, radius = r, slant height = l

We know that, in a right triangle, one angle is equal to 90° Using Pythagoras theorem, we know that:

\left ( \text {hypotenuse} ^{2}=\text {base}^{2}+\text {height}^{2}\right )

l^{2}=h^{2}+r^{2}

Thus the statement is False.
