Sarah and Homer each have a cylinder. Sarah's cylinder has a diameter of 9 cm and a height of 4 cm. Homer's cylinder has a diameter of 4 cm and a height of 9 cm. Find the surface area of Sarah's cylinder, in square centimetres. Round your answer to two decimal places. answer fast plz its urgent

Step-by-step explanation:

The question is on the mensuration of solids, a cylinder

Given data

height of cylinder h= 4 cm

diameter d= 9 cm

radius = d/2= 9/2= 4.5 cm

we know that the surface area of cylinder is

Substituting our data into the expression we have

Therefore the total surface area is 240.37 cm^2
