A circular park of 28m diameter has been constructed.
The radius of the parK = 14 m
:
A 3.5m circular track outside has been developed along the park.
The overall radius, track and the park: 17.5 m
:
Using algebraic formulae, find the area of the track around the park
:
Track area (A) = overall area - park area
A = -
A = -
Factor out pi
A =
A =
A = 346.36 sq/m
