Question

the diameter of a wheel is 2.1 metre. find the distance covered by it in 650 revolution​

Answer 1

Answer:

$\huge{\tt{Answer}}$

Diameter of wheel = 2.1 m

Radius = 1.05 m

Number of revolution = 650

According to formula ,

$\red{\tt{No. of Revolution = Distance travelled in one minute / Circumference}}$

Therefore , distance travelled ___

= 650 × 2π r m

= 650 × 2 π × 1.05 m

= 42 , 900 m

$\huge{\tt{\red{Distance}}}$ =

$\huge{\red{\tt{ 42900 metres}}}$

Answer 2

$\huge\tt{SoLution:-}$

Given that :-

★ Diameter = 2.1metre

Radius = 1.05meter

★ Distance covered = 650

Then according to questions:-

using formula,

Circumference of the wheel = 2πr

= 650 × 2π × 1.05

= 42,900 meter
