Problema Solution
A circular fountain of 5m radius lies alone in the center of a circular park of 700m radius. Calculate the total walking area a available to pedestrians visiting the park.
Answer provided by our tutors
the total walking area available = the area of the park (circle with radius 700 m) - the are of the fountain (circle with radius 5 m)
the total walking area available = 700^2*pi - 5^2*pi
the total walking area available = (700^2 - 5^2)*pi
the total walking area available = 489975*pi
the total walking area available = 1,538,521.5 m^2
the total walking area available to pedestrians visiting the park is 1,538,521.5 m^2.
