Question

plzz answer the attached question

Answer 1

Radius of cylinder(r)= 56/2 = 28m
Height of cylinder(h) = 6m
Area of cylinder = 2 pie r h = 2×22/7×28×6 = 1056m^2

Radius of cone(r) = 56/2 = 28m
Height of cone(h) = 30-6 = 24m
slant height of cone(l) = ?
l^2 = r^2 + h^2
l^2 = (28)^2 + (24)^2
l^2 = 784 + 576
l^2 = 1360
l = \/(1360)
l = 36.88m
Area of conical roof = pie r l = 22/7×28×36.88 = 3245.44m^2

Total area of canvas = Area of cylinder + Area of conical roof = (1056 + 3245.44)m^2 = 4301.44m^2
