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

tube or goog would be a great resource to with that question
