Question 1092753: The diameter of base of a chimney is 80cm. height is 12.5 m. What will be the cost of painting this chimney from outside at the rate of Rs 140 per square metre? π=3.14 Answer by ikleyn(52835) (Show Source):
The cost will be the product of the lateral surface of the chimney (cylinder) by the cost of painting of 1 sq. meter.
Use uniform (consistent) dimension units !
The total cost = pi*D*h*rate = rs.
You do all necessary calculations.
