Question

Instructions: Find the surface area of each figure. Round your answers to the nearest tenth, if necessary. 4 cm. 1 cm. Surface Area: cm?

Answer 1

The solid shape is a cylinder

The surface area, A of a cylinder is given by the areas of its two bases and side mathematically given as:

`A\text{ = 2}\pi r^2+2\pi rh`

where A = area

r = radius = half of diameter

h = height

We are given the diameter to be 4cm, therefore, radius is 4/2 = 2 cm

Therefore, the surface area of the cylinder is given as:
