Question

a car movings with the speed of 22 dacameter pee second find the daimeter of a wheel if it proforms 700 revolution per secon
​

Answer 1

Answer:

Step-by-step explanation:

Each revolution of the wheel travels the circumference C, so 700C = 22 dam = 220 m = 22000 cm

C = 22000/700 = 220/7 = 2πr = πd Since π is roughly 22/7, the wheel diameter is roughly 10 cm (which are some pretty small wheels)

Answer 2

Step-by-step explanation:

A car is moving with the speed of 22 decimeter per second.

Let r be the radius of the wheel.

Therefore, distance covered by the wheel in 1 revolution=2πr dm

Distance covered in 7 revolution=14πr dm

Speed =14πr/1 =22/1

=>14×22/7xr=22

r=1/2 dm

Therefore, diameter =1dm =0.1m
