Question

Volume of cone formerd by an equilateral triangle of side 10 cm

Answer 1

Volume of the cone = 1/3 (PI*R*R*H)

Since the cone is formed from by an equilateral triangle, all sides are equal that is slope = diameter = 10

So, height = (10^2) - (5^2) = ?75 [by hypotenuse theorem]

=> Height = 8.66

Volume = 1/3(8.66*3.14*25)

=> Volume = 226.61 cm^3
