Formula of the Volume of a hemisphere:
V =


r³
144

=


r³
Multiply by 3 to cancel fraction in the right side
144

× 3 = 2

r³
432

= 2

r³
Divide by 2

on either sides to isolate r³

=

r³
2

and

cancel out
216 = r³
Take cube root to find the radius
![\sqrt[3]{216}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B216%7D%20)
=
![\sqrt[3]{r^3}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7Br%5E3%7D%20)
6 = r
Radius is 6 unitsThe formula of the surface area of a hemisphere is:

Answer:
Defining the straight number of integers, we have to live in the year 2020 and this Greek historian was born in the year - 484.
Step-by-step explanation:
When using whole numbers, we denote positive numbers as the number of numbers after 0, and negative numbers the number of numbers before zero.
So if we consider the birth of Christ to be the year 0, then all years before Christ will be negative and all years after Christ will be positive.
So we have to live in the year 2020 and this Greek historian was born in the year - 484.
