Perimeter and A...

The difference in the area of a square of perimeter $$88$$ m and a circle with same circumference is

The ratio of the outer and inner circumferences of a circular path is $$23:22$$, If the path is $$5\ m$$ wide, the radius of the inner circle is: 

The radius of a circle whose area is equal to the sum of the areas of two circles of radii 3 cm and 4 cm is

Area of a square 625 sq m. Then the measure of its side is

The radius of a circle whose area is equal to the sum of the areas of two circles of radii are  5 cm and 12 cm is

Find the perimeter of a circle whose radius is 7 cm (in cm)

If the area of the circle be $$ \displaystyle 154 \text{ cm}^{2},$$ then its radius is equal to:

If the circumference of a circle be $$8.8 \text{ m}$$ then its radius is equal to -

If the radius of a circle be $$r$$ $$ cm$$, then its area will be equal to-

What is the circumference of a circle whose radius is 8 cm?
