A road bike has a wheel diameter of 622 mm. What is the circumference of the wheel? Use 3.14 for mc015-1.jpg
Answer: 1953.08 mm
Step-by-step explanation:
We know that circumference of a circle is given by ;-
\(\text{Circumference}=2\pi r\), where r is the radius of the circle.
Given: the diameter of the wheel = 622 mm
Then, the radius of the wheel =\(\dfrac{622}{2}=311\ mm\)
Now, the circumference of the wheel is given by ;-
\(\text{Circumference}=2\pi (311)\\\\\Rightarrow\ \text{Circumference}=2(3.14)(311)\\\\\Rightarrow\ \text{Circumference}=1953.08\ mm\)
Hence, the circumference of the wheel = 1953.08 mm.
The circumference of the wheel is equal to 1,953.08 mm.
Given the following data:
To calculate the circumference of the wheel:
Note: A wheel of a bike is circular in shape.
Mathematically, the circumference of a circle is given by the formula:
\(Circumference = \pi D\)
Where:
Substituting the given parameters into the formula, we have;
\(Circumference = 3.14 \times 622\)
Circumference = 1,953.08 mm.
