In a sphere of radius r, a right circular cone of height h having maximum curved surface area is inscribed area is inscribed.

Correct option is: A) 1848 cm2 We have r = Base radius of cylinder = 14 cm h = Height of the cylinder = 21 cm. \(\therefore\) Curved surface area of cylinder = 2 \(\pi rh\) = \(2...

Correct option is: B) 4 : 4 : √5 Given that  Radius of cylinder = Radius of cone = Radius of sphere = r \(\because\) Height of the sphere = Diameter of the sphere =...

Correct option is: A) 264 cu.cm We have r = Radius of the cone = 6 cm and h = Height of the cone = 7 cm. \(\therefore\) Volume of cone = \(\frac 13 \pi r^2h\) = \(\frac 13...

Correct option is: C) slant height of the cone Lateral surface are of a right circular cone = \(\pi rl\) Where r = Radius of the base of the cone and l = Slant height...

Correct option is: A) 405 π We have  r = Radius of base of the cone = 9 cm, h = Height of the cone = 15 cm. \(\therefore\) Volume of cone = \(\frac 13 \pi r^2...
