Question

a circular wheel completes 4 revolutions to cover a distance of 880 cm what will be the radius of that wheel​

Answer 1

Answer:

Radius is 35

Step-by-step explanation:

1.Revolutions means circumference of the circle is given

2.so we have to find 1 revolution first that will be 880÷4=220

3.now to find the radius

4.Formula of circumference is 2×pie×r

5.so 2×pie×r=220

6.2×22÷7×r=220

7. 44÷7×r=220

8. 7×220=1540÷44

9. 1540÷44

10. Radius is 35

11.Proof=circumference =2×22÷7×35=220

12. 4 revolutions so 2×4×22÷7×35=880
