lana66690 [7]

Answer:

The area of hub cap is 452.16 square centimeters.                                    

Step-by-step explanation:

We are given the following in the question:

Radius of hubcap = 12 cm

A hubcap is of the shape of circle.

Area of hubcap = Area of circle

Area of hubcap =

\pi r^2

where r is the radius of the hubcap.

Putting the values, we get,

\pi r^2\\= 3.14\times (12)^2\\= 452.16 \text{ square centimeter}

Thus, the area of hub cap is 452.16 square centimeters.

Use a two-dimensional representation of the prism, if necessary, to find the area of the entire surface of the prism.
lyudmila [28]

Answer:

The surface area of the prism is 72 square units.

Step-by-step explanation:

In order to calculate the surface area of the prism we must calculate the area of each face of the prism. To better visualize it we can look at the picture below. We must calculate the area of every face in the picture, so we have:

surface area = 2*[(1/2)*3*4] + 3*5 + 4*5 + 5*5

surface area = 12 + 15 + 20 + 25

surface area = 72 square units
