Diameter of the circular park =30m
therefore it's radius= 30/2= 15 m
(radius =diameter/2)
Surface area of a circle = πr² sq.units
= 22/7 × (15)²
=22/7 × 225
=4,950/7
=707.14
or
= 707 m².
Thank You!!!
All the best.☺️

Answer:
The diameter is 30m
The radius r= 1/2 X 30m (diameter)
=15m
The surface area is π²
when the pie is 3.14 it will be
3.14 X 15 ²= 706.5 m²
