Find The area of a Circular path if its radius R is 3.5

a curve has area zero, regardless of it radius. It's just a line.

A = pi*R^2.

To find the area of a circular path with radius R, you can use the formula for the area of a circle, which is A = πR^2.

In this case, the given radius is 3.5, so we substitute this value into the formula:

A = π × (3.5)^2

A = π × 12.25

A ≈ 38.48 square units

Therefore, the area of the circular path with a radius of 3.5 is approximately 38.48 square units.
