Answer 1

base = 6 & height = 8 is given Area of one triangle = LX 6X8 Given a paint moller is 18 inch long with ta inch radius A paint nollen has a shape of cylinder The lateral area of a cylinder is given 27 Rh 01 Hence the total area 24 X8 = 192 in 2 Hence 192 in wood is needed to replace the entire roof. where and he is R is the radius of the cylinder the height of the uglinder area of paint coller Hence lateral is MX1 X LX 18 18 T in 2 2.2 A right pyramid on top of a rectangular octagon is given A right pyramid rectangular octagon. has 8 triangular surface nehich are identical in shape. Area of one triangle = 1 x base x height
