Answer: 1719.22 mi squared
Explanation:
you have to find the height first.
you only have r and hypotenuse
so
a^2 + b^2 = c^2
13^2 + b^2 = 29.1^2
169 + b^2 = 846.81
b^2 = 846.81 - 169
b^2 = 677.81
b = 26.03
height = 26.03
surface area formula :
_______
πr(r+_/h^2+r^2)
___________
π(13) [13 + _/26.03^2 + 13^2]
= 1719.22
