Answer:
area of the top surface= 57m²and distance around it = 27m
Explanation:
as given diameter = 8.5 meters (radius = diameter/2)
area of a circular pond is given by a= πr² (where π= 22/7 and r= d/2 radius of the circular pond)
a= 22/7 * (8.5/2)²
a= 22/7 * (4.25)²
a= 22/7 * (18.0625)
a= 56.76≅ 57 m²
Circumference of the circular pond= 2πr
=2(22/7) (4.25) = 26.71≅ 27m
