Question : A copper sphere of diameter 18 cm is drawn into a wire of diameter 6 mm. Find the length of the wire.
Option 1: 143 m
Option 2: 108 m
Option 3: 324 m
Option 4: 234 m
Correct Answer: 108 m
Solution : Diameter of sphere = 18 cm Radius of sphere, $R$ = 9 cm Diameter of wire = 6 mm The radius of wire, $r$ = 3 mm = 0.3 cm Let $l$ be the length of the wire. Volume of sphere = volume of
Question : In a triangle ABC, $\angle A = 70^{\circ}, \angle B = 80^{\circ}$ and D is the incentre of $\triangle ABC. \angle ACB = 2 x^{\circ}$ and $\angle BDC = y^{\circ}$ The values of x and y, respectively, are:
Option 1: 15 and 130
Option 2: 15 and 125
Option 3: 35 and 40
Option 4: 30 and 150
Correct Answer: 15 and 125
Solution : Given: $\angle A=70^{\circ},\angle B=80^{\circ}$, $\angle ACB = 2x^{\circ},$ and $\angle BDC = y^{\circ}$ $\angle C = 180^{\circ}-70^{\circ}-80^{\circ}=30^{\circ}$ $\therefore \angle ACB = 2x^{\circ} = 30^{\circ}$ $⇒x=15^{\circ}$ Now, $\angle BDC=90^{\circ}+\frac{1}{2}\angle A^{\circ}$ ⇒ $y=90^{\circ}+\frac{1}{2}\angle 70^{\circ}$ $\therefore y=125^{\circ}$ Hence, the correct answer is 15 and 125.
Question : Directions: Select the option figure that is embedded in the given figure (rotation is NOT allowed).
