A circluar wheel has a radius of 10cm how far will it roll in 7 revolution
The distance around the outside (the roll) is (pi)(d) where d = 2r, so
(pi)(2)(r)
Since your wheel is making 7 revolutions it is
= 7(pi)(2)(r)
Thank you very much
To find out how far a circular wheel will roll in a given number of revolutions, we need to calculate the circumference of the wheel and then multiply it by the number of revolutions.
The circumference of a circle can be found using the formula: C = 2πr, where C is the circumference and r is the radius of the circle.
In this case, the radius of the wheel is given as 10 cm. Thus, the circumference can be calculated as follows:
C = 2π(10)
C = 20π cm
Now, we need to multiply the circumference by the number of revolutions (in this case, 7) to find the total distance rolled:
Distance rolled = 7 * 20π
Distance rolled ≈ 44π cm
Therefore, the wheel will roll approximately 44π cm in 7 revolutions.
