Besides, diameters and circumferences of all the solar mandalas are also stated in SP 1.8 as ;
i.e., “When the Sun treads upon the innermost mandala (Sun's diurnal circle on Summer solstice day), the mandala has Yojanas thickness (north-south breadth of the strap of diurnal path described by the solar disc), 99640 yojanas diameter and a slight more than 315089 yojanas circumference.
48 “..... Second to the innermost mandala, . .... ** Yojanas thickness,
99645 yojanas diameter and a slightly less than 315107 yojanas circumference.
“Likewise, treading upon mandala to mandala, when the Sun moves on the outermost mandala (Sun's diurnal circle on Winter solstice day),
the mandala has Yojanas thickness, 100660 yojanas diameter and 318315 yojanas circumference.”
The dimensions of solar mandalas can easily be computed as follows:
Diameter
Radius =
RMA = PM
... (11)

Where Rm. = Radius of the M, (nth solar mandala) or
Dan = Diameter of Ma Now for the innermost solar mandala M, we have RM, = 9040 = 49829 y
= 44820 y +5000 y = NPD of My+Radius of Meru's base on flat earth.
Analogically, we have
RM = NPD of Mn+Radius of Meru's base on flat earth.
