Answer:
about 210.5 ft²
Step-by-step explanation:
The radius of the base of the tent is half the distance across, so is 13/2 = 6.5 ft. The slant height (s) of the tent is found using the Pythagorean theorem:
s = √(6.5² +8²) = √106.25 ≈ 10.308 ft
Then the lateral area can be found from the formula ...
LA = πrs = π·(6.5 ft)(10.308 ft) ≈ 210.49 ft²
