Question

TSA = 1232m^2 ,Height = 21m find diameter​

Answer 1

Answer:

The object is cylinder

TSA = 2πr(r+h)

1232 = 2*22/7*r(r+21)

(1232*7)/44 = r^2+21r

28*7 = r^2+21r

196 = r^2+21r

r^2+21r-196 = 0

r^2+28r-7r-196 = 0

r(r+28)-7(r+28) = 0

(r-7)(r+28) = 0

r = 7,-28

Radius can't be negative So r = 7m

Diameter = 14m
