1) It has only two dimensions .   FALSE

2). Its cross section is in the shape of a circle .   TRUE

3) Its surface area is measured in cubic units.      FALSE

4) It has a radius that is always a perfect square.     FALSE.

Step-by-step explanation:

Sphere: Sphere is a 3 dimensional perfectly round object.

Here, all point lying at the circumference are at equal distance from the center.

The given statements are:

1) It has only two dimensions .

FALSE, a 2 D figure is a circle not a sphere. Sphere is 3 D.

2). Its cross section is in the shape of a circle .

TRUE, any cross section of a sphere is always a circle.

3) Its surface area is measured in cubic units.

FALSE, Surface area of a sphere =  sq. units

4) It has a radius that is always a perfect square.

FALSE. A sphere can be of any possible radius.
