A solid sphere of radius $1 \mathrm{~cm}$ is melted to convert into a wire of length $100 \mathrm{~cm}$. The radius of the wire (using $\sqrt{3}=1.732$ ) is:

The one-meter-wide path is built inside a square park of side $30 \mathrm{~m}$ along its sides. The remaining part of the park is covered by grass. If the total cost of covering by grass is Rs 1176, find the rate per square meter at which the park is covered by the grass.

Ratio of sides of a triangle is $17: 8: 15$, If perimeter is $96 \mathrm{~cm}$ then find the area of triangle.

Find the circumference of a circle whose area is 1232 $\mathrm{m}^{2}$.
