Question

Sort the following according to length in descending order ( top to bottom).

• A. Circumference
• B. 270° arc
• C. Radius
• D. Diameter

Answer 1

The correct option is
Smallest will be radius
Diameter = 2$\times$radius
Length of Arc subtending angle 270° = $\frac{3\pi }{2}\times radius$ = 4.71$\times$radius
Circumference = 6.28$\times$radius

Hence order will be
Radius < Diameter < 270° arc < Circumference.
