Solution: 7, 24 and 25 is a Pythagorean triplet.When a triangle is rotated about one of its perpendicular sides then a cone is formed in space. To maximize this volume we need to maximize r2. So if the cone is rotated about the 7 cm side, we will get r as 24. This would give the maximum volume. 1 Crore+ students have signed up on EduRev. Have you?
