Find the height of a cone of area 550cm square and base radius 7cm square ,taking π to be 22/7.

Answer 1

I assume the lateral surface area = 550 cm^2

area = πrs, where s is the slant height
550 = π(7)s
s = 550/(7π) = 550/(7(22/7)) = 550/7 cm

h^2 = 7^2 + (550/22)^2 = 7^2 + 25^2
finish the arithmetic calculations

Answer 2

24 is the final answer
