Step-by-step explanation:
We have,
Diameter of cylinder, d = 39.2 mm
Radius, r = 19.6 cm
Height of the cylinder, h = 39.2 mm
It is required to find the surface area of this cylinder. The formula of the surface area of cylinder is given by :
Putting all values we get :
Multiply 2/1 or 2 on both sides to get "y" by itself
y ≤ -14
