Answer 1

The circumference of the wheel is 4.398 m

Step-by-step explanation:

Given:

The diameter of wheel is 1.4 m.

To find:

Wheel's circumference

Solution:

Diameter = 1.4 m

Radius = diameter/2

$= \frac{1.4}{2}$

= 0.7 m

Circumference = $2 \pi r$

=$2 \pi \times 0.7$

= 4.398 m .

Answer 2

Answer:

$\red { Circumstance \: of \: the \:wheel }\green{=0.44:m }$

Step-by-step explanation:

$Diameter \: of \:the \: wheel (d) = 1.4\:m$

$\red { Circumstance \: of \: the \:wheel }=\pi d$

$= \pi \times 1.4$

$= \frac{22}{7} \times 1.4\:m$

$= 22 \times 0.2$

$= 0.44 \:m$

Therefore.,

$\red { Circumstance \: of \: the \:wheel }\green{=0.44:m }$
