If a circular fish pond measures 8.5 meters across what is the area of the top surface and what is the distance around it

area of the top surface = 57m²and distance around it = 27m

Step-by-step 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
