Question

th diameter of wheel of car is 35 cm how much distance will cover in 1000 revolution

Answer 1

Diameter of wheel =35cm
Radius of wheel =35/2 =17.5 cm
Circumference of wheel =2×22/7×r =2×22/7×175/10 =110 cm

Thus,
The wheel will cover 110×1000 =110000cm or 1.1 km

Hope it will help u...
Plz mark it as brainliest answer...

Answer 2

$\star\small\sf\underline\blue{Given:-}$

$\star\small\sf\underline\blue{Find \: Out:-}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀

• The distance covered in 1000 revolutions = ?

$\star\small\sf\underline\blue{Solution:-}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀

• Diameter off the wheel = 35 cm

$\footnotesize\bold{\underline{\underline{\sf{\red{Therefore:-}}}}}$

$\sf \: Circumference = 2\pi \: r \\ \: \sf \: Circumference = \: \pi d \bigg(\because d = 2r \bigg) \\ \\ \\ \sf \: Circumference = \dfrac{22}{ \cancel7} \times \cancel{35} \\ \\ \sf \: Circumference =22 \times 5 \\ \\ \sf \: Circumference =\large{\boxed{\bf\blue{110 \: cm }}}$

$\footnotesize\bold{\underline{\underline{\sf{\red{Therefore:-}}}}}$

Distance covered in 1000 revolutions

$\: \: \: \: \: \: = \sf110 \: cm \times 1000 \\ \\ \: \: \: \: \: \: = \sf110000 \: cm \\ \\ \: \: \: \: \: \: = \sf \cancel\dfrac{110000}{100000} \: km \\ \\ \: \: \: \: \: \: =\large{\boxed{\bf\blue{1.1 \: km}}}$
