Question
Find the total surface area of a cone with a height of 12cm and a radius of 5cm
Answers
GPT 3.5
Total surface area of a cone = πr(r+√(r^2 + h^2))
Given:
Height (h) = 12 cm
Radius (r) = 5 cm
Total surface area = π*5(5+√(5^2 + 12^2))
Total surface area = π*5(5+√(25 + 144))
Total surface area = π*5(5+√169)
Total surface area = π*5(5+13)
Total surface area = π*5*18
Total surface area = 90π cm^2
Therefore, the total surface area of the cone is 90π square cm.
