Question

A hubcap has a radius of 12 centimeters. What is the area of the hubcap? Round your answer to the nearest hundredth. Use 3.14 for π.

Answer 1

The area of the hubcap is about 452.16 cm².

Explanation:

A = πr²

Use the formula.

A = π(12)²

Substitute. Use 12 for r.

A ≈ 3.14 × 12²

Substitute. Use 3.14 for π.

A ≈ 3.14 × 144 Evaluate the power.

A ≈ 452.16 Multiply.

Answer 2

The area of hub cap is 452.16 square centimeters.

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* (12)^2\\= 452.16 \text{ square centimeter}`

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