Question : If the height and slant height of a cone are 21 cm and 29 cm, respectively. Find its volume. (Use $\pi=\frac{22}{7}$)
Option 1: 8800 cm3
Option 2: 8708 cm3
Option 3: 8440 cm3
Option 4: 8080 cm3
Correct Answer: 8800 cm3
Solution : Given, height $= h = 21\ \mathrm{cm}$ Slant height $=l=29\ \mathrm{cm}$ Let $r$ be the radius. We know, $l^2=h^2+r^2$ ⇒ $r^2=l^2-h^2$ ⇒ $r^2=29^2-21^2$ ⇒ $r^2=841-441$ ⇒ $r^2=400$ ⇒ $r=20$ cm Now, Volume $=\frac{1}{3}\pi r^2h$ $=\frac{1}{3}\times\frac{22}{7}\times(20)^2\times21$ $=\frac{1}{3}\times\frac{22}{7}\times400\times21$ $=8800$ cm3 Hence, the correct answer
Question : A solid metallic sphere of radius 6.3 cm is melted and recast into a right circular cone of height 25.2 cm. What is the ratio of the diameter of the base to the height of the cone?
Option 1: 2 : 1
Option 2: 3 : 2
Option 3: 1 : 2
Option 4: 2 : 3
Correct Answer: 1 : 2
Solution : The radius of the sphere ($R$) = 6.3 cm The height of the cone ($h$) = 25.2 cm Volume of sphere = $\frac{4}{3} \pi R^3$ Volume of cone = $\frac{1}{3} \pi r^2h$ According to the question $\frac{4}{3} \pi R^3$ = $\frac{1}{3} \pi r^2
