Question

the diameter of a wheel is 70 cm . find the distance covered by the wheel in 5 revolutions.​

Answer 1

Answer:1100cm

Step-by-step explanation: Circumference Of The Wheel = 2πr

Radius-) 70/2cm = 35cm.

Circumference= 2×22/7×35 = 220cm.

No. Of Revolution-) 5

So, No. Of Revolution= Distance Covered ÷ Circumference

Hence, 5 = Distance Covered ÷ 220

Distance Covered= 5×220 = 1100cm.

Answer 2

1.1 metres

Given:

• diameter of a wheel is 70 cm
• No of revolutions 5

To find :

• The distance covered by the wheel in 5 revolutions.

Solution:

$d = 70 \\ \\ \implies \: r = 30 \: units$$circumference \: of \\ \: a \: circle \: = 2\pi \: r \\ \\ \implies \: 2 \times \dfrac{22}{7} \times 35 \: units \\ \\ \implies \: 2 \times 22 \times 5 \\ \\ \implies44 \times 5 = 220cm$

Total distance travelled in 5 revolution =

» 220 x 5

» 1100 cm

» 1.1m

distance travelled is 1.1 metres
