Define Diameter of Sphere:
A non-Euclidean geometry in which is the study of figures on the surface of a sphere
the length of a segment passing through the center of the sphere, with endpoints on the sphere. The diameter of a sphere is
equal to the diameter of great circle in the sphere.
the study of plane and solid figures on the basis of axioms and theorems
a circle on a sphere that divides the sphere into two equal hemispheres

for this case we have the following expression:

to solve, we rewrite the expression as:

we apply double c and we have:

thus, the quotient is 48.

so, patel found a wrong ratio and the multiplication was incorrect.

option d

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
