Question

the diameter of a bicycle wheel is 28 cm . what distance will it cover in 100 revolutions



answer is 88 m

Answer 1

Diameter=28cm
then radius=14cm
now...
2(pi)r
2×22/7×14
88cm
now...
revolutions are 100
so...
100×88 cm
8800 cm
means...
88 m

Answer 2

Answer:

8800cm or 88m

Step-by-step explanation:

Diameter: 28 cm

Radius: 28/2= 14cm

Find the perimeter of the circle.

Circumference of a circle= 2 * 22/7 * 14 (r)

                                          =88cm

Now, the perimeter is 88cm

It is understood that the perimeter of the whole circle is equal to only one revolution since the perimeter borders the circle once that we call as PERIMETER.

1 revolution = 88cm

100 revolutions= ?cm

88*100= 8800cm

It can be written as 8800cm or 88m.
