Question

Diameter of wheel cart is 280 m find distance cover by cart in 20 complete revolution?

Answer 1

Given:-

• Diameter of wheel cart = 280m

• No. of revolution = 20

To Find:-

• Distance covered by cart in 20 complete revolution.

Formula Used:-

• ${\boxed{\bf{Radius=\dfrac{Diameter}{2}}}}$

• ${\boxed{\bf{Circumference=2\pi r}}}$

Solution:-

Firstly,

$\sf :\implies\:Radius=\dfrac{Diameter}{2}$

$\sf :\implies\:Radius=\dfrac{280}{2}$

$\sf :\implies\:Radius=140\:cm$

Now,

$\sf :\implies\:Circumference=2\pi r$

$\sf :\implies\:Circumference=2\times \dfrac{22}{7}\times140$

$\sf :\implies\:Circumference=2\times22\times20$

$\bf :\implies\:Circumference=880\:cm$

Distance covered by cart in 20 complete revolution:-

$\sf :\implies\:880\times20$

$\sf :\implies\: 1,760\:m$

Hence, Distance covered by cart in 20 complete revolution is 1,760m.

Answer 2

Answer:

Given:-

d. of wheel cart = 280m

$\therefore \: radius \: = \: \frac{280}{2} \\ \\ = 140$

No. of revolutions = 20

To Find:-

Distance covered by the cart .

Solution:-

Circumference = 2πr

= 2 × 22/7 × 140

=2×22×20

= 880 cm

=> Distance covered by cart in 20 complete revolution = 880×20 = 1,760 cm

We know,

1 m. = 1×100 cm.

1 cm. = 1/100 m.

=> 1760 cm. = 1760/100 m. = 17.6 m.

Hence, the Total Distance covered by the cart in 20 complete revolutions is 17.6 m.
