Question
sir or ma,please help me figure-out a solution to this:(1)find the diameter of a circukar field whose area is 616m^2
(2)the volume of a cube is 512cm^3.find its total surface area.

"The area of a circular field is 616 m²"
area = πr², where r is the radius
πr² = 616
r² = 616/π
r = √(616/π) = 196.1 m

diameter = 2r = 392.2 m
:::::
"The volume of a cube is 512 cm³"
The length of an edge of the cube is ∛512 = 8 cm

Area of one face of the cube = 8² = 64 cm²
A cube has six congruent faces, so the total surface area is 6×64 = 384 cm²
