Please answer ASAP.. Awheel has a diameter of 16 cm.
Approximately how far does it travel in 5 revolutions?
A.
502.4 cm
B.
251.2 cm
C.
100.48 cm
D.
80 cm
B.
251.2
πd * 5 = 3.14 *16 * 5 = 251.2
Yep!
To find the distance traveled in 5 revolutions, we need to calculate the circumference of the wheel and then multiply it by the number of revolutions.
The formula to calculate the circumference of a circle is C = πd, where C is the circumference and d is the diameter.
Given that the diameter of the wheel is 16 cm, we can calculate the circumference as follows:
C = π * 16 cm = 16π cm
To find the distance traveled in 5 revolutions, we multiply the circumference by the number of revolutions:
Distance = 5 * 16π cm
It is important to note that π is an irrational number and is approximately 3.14159.
Let's calculate the distance:
Distance = 5 * 16 * 3.14159 cm
Simplifying the expression:
Distance ≈ 251.2 cm
Therefore, the answer is B. 251.2 cm.
