Question : The side of a square is equal to 40% of the radius of a sphere. If the volume of the sphere is $\frac{500 \pi}{3} \mathrm{~m}^3$, then what is the area of the square?

Option 1: 2 m2

Option 2: 1 m2

Option 3: 9 m2

Option 4: 4 m2

Team Careers360 23rd Jan, 2024

Correct Answer: 4 m2


Solution : The Volume of a sphere is $\frac{500\pi}{3}$ m$^3$.
Side of square = 40% radius of the sphere
Area of square = Side$^2$
According to the question,
The volume of a sphere =  $\frac{4}{3}\pi r^3$
⇒ $\frac{4}{3}\pi r^3$ = $\frac{500\pi}{3}$
⇒ $r^3$ = $\frac{500}{4}$

Question : A man can swim at a speed of 14 km/hr in still water. If he takes twice the time as long to swim opposite the flow of the river than with the flow of the river, find the rate of the stream in km/hr.

Option 1: $\frac{14}{5}$

Option 2: $\frac{11}{5}$

Option 3: $\frac{11}{4}$

Option 4: $\frac{14}{3}$

Team Careers360 23rd Jan, 2024

Correct Answer: $\frac{14}{3}$
