A bicycle has a radius of 28cm
How far does it travel in four complete turns
I assume you mean that the wheel has a radius of 28 cm.
C = pi * d
C = 4.14 * 56
C = ?
How far does it travel in four complete turns?
4C = ?
To calculate the distance traveled by the bicycle in four complete turns, we need to find the circumference of its wheel and multiply it by the number of turns.
1. The circumference of a circle can be found using the formula: C = 2πr, where C is the circumference, π is a constant approximately equal to 3.14159, and r is the radius of the circle.
2. Substituting the given radius into the formula, we have: C = 2 * 3.14159 * 28 cm.
3. Simplifying the equation, we get: C ≈ 175.93 cm.
4. Since the bicycle completes four turns, we multiply the circumference by 4: D = 4 * C.
5. Substitute the value of C into the equation: D = 4 * 175.93 cm.
6. Calculating the equation, we find: D ≈ 703.72 cm.
Therefore, the bicycle will travel approximately 703.72 cm in four complete turns.
To calculate the distance a bicycle travels in four complete turns, we need to find the circumference of the circle that the bicycle travels in during one turn, and then multiply it by four.
The circumference of a circle can be found using the formula:
C = 2πr
where C is the circumference and r is the radius.
In this case, the radius of the bicycle is given as 28cm. Therefore, we need to calculate the circumference of the circle using the formula:
C = 2π(28cm)
We can simplify this by substituting the value of π as approximately 3.14:
C ≈ 2 × 3.14 × 28cm
Now we can calculate the circumference:
C ≈ 6.28 × 28cm
C ≈ 176.72cm
Now that we have the circumference, we need to multiply it by four to find the distance the bicycle travels in four complete turns:
Distance = Circumference × Number of Turns
Distance ≈ 176.72cm × 4
Distance ≈ 706.88cm
Therefore, the bicycle travels approximately 706.88cm (or 7.07m) in four complete turns.
