Question

the diameter of a car's tyre is 70 cm find the distance covered by it in 5 rounds (pi=22/7)​

Answer 1

Step-by-step explanation:

Distance covered by the car in 5 rounds=1100 cm or 11 m

Given:-

The diameter of a car's tyre is 70cm

To find:-

.Find the distance covered by it in 5 round's (pi=22/7)

Solution:-

The diameter of the tyre=70cm

Radius of the tyre=diameter/2

Radius=r=70/2=35cm

Using Concept:-

tyre is in the form of circle If it is distance covered by one round is the perimeter of the tyre

Perimeter of the circle=2πr

Distance covered by the car in one round

=2×(22/7)×35

=>(2×22×35)/7

=>2×22×5

=>220cm

Distance covered by the given car in one round=220cm

Distance covered by the car in 5 rounds

=>5×220

=>1100 cm 11 m (100cm=1m)

Answer:-

Distance covered by the car in 5 rounds=1100cm or 11 m

Answer 2

Step-by-step explanation:

The diameter of the tyre=70cm

Radius of the tyre=diameter/2

Radius=r-70/2=35cm

Using Concept

tyre is in the form of circle If it is distance

covered by one round is the perimeter of the

tyre

Perimeter of the circle=2Tr

Distance covered by the car in one round

-2x(22/7)x35

=>{2*22*35)/7

>2*22*5

->220cm

Distance covered by the given car in one

round-220cm

Distance covered by the car in 5 rounds

5 220

-1100 cm 11 m (100cm-1im)

Answer:

Distance covered by the car in 5

rounds=1100cm or 11 m
