because triangle's will have square numbers in it too.
Incorrect. Square numbers are composite and have an odd number of factors.
A circle is not a number, it is a 2-dimensional shape. A number can have a square root, not a shape. So, a circle cannot have a square root!.
Divide by pi then divide by 2 then square the number and then multiply by pi
16.25 cm will be the radius of the circle (32.5 divided by 2) Area of a circle = pi*radius2 = pi*16.252 = 51.05088062 square centimetres So the answer is 51 square metres correct to two significant figures.
The radius is 9 inches because area of circle is pi*9 squared = 81pi square inches and the diameter is twice the radius which is 2*9 = 18 inches

The number of square corners in a circle is infinite because it has no definite angle.

If the circle is inside the square, four.
When you square a real number the answer is positive,
Let's call the number 'K' ... the side of the square and the radius of the circle.-- the area of the square is [ K2 ]-- the area of the circle is [ (pi) K2 ]-- The ratio of the circle to the square is [(pi) K2 / K2 ] = pi
The correct answer is "perfect square".
78.54 cubic centermeters * * * * * Correct number, wrong units. Areas may be measured in SQUARE centimetres, not cubic centimetres.
That would depend on its radius because the area of a circle is pi times radius squared
Area of a circle = pi*radius2
to find out if the number is a square number when you see a whole number written and on top of it there is a small number written two
