3 Dimentional Figures

3 dimensional figures:
Find the surface area of the cylinder when the area of the cylinder is 157 cm² and the radius and height is 5 cm and 7 cm respectively.
Given: Area = 157 cm²
Radius = 5 cm
Height = 7 cm
Sol:
Formula: 2Пr² + 2Пrh = 157 + 2П5(7) =157 + 219.8 = 376.8 cm^{2
