A wire is in the form of a circle of radius 70 cm. If it is bent in the form of a rhombus, then what is its side length? (Take π = 22/7)
Elementary MathematicsMensuration
- A55 cm
- B75 cm
- C95 cm
- D110 cm
Explanation
The wire's length is the circle's circumference: 2π·70 = 440 cm (using π = 22/7). Bent into a rhombus, this is the perimeter, so each side is 440/4 = 110 cm. Hence option D.
