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 =
[tex]\pi r^2[/tex]
where r is the radius of the hubcap.
Putting the values, we get,
[tex]\pi r^2\\= 3.14\times (12)^2\\= 452.16 \text{ square centimeter}[/tex]
Thus, the area of hub cap is 452.16 square centimeters.
Answer:
The area of the hubcap is about 452.16 cm².
Step-by-step 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.
