Question

the diameter of Ravi bicycle tyre measure 63cm how far does the bicycle move when the wheel make one complete revolution​

Answer 1

Step-by-step explanation:

distance covered =2πr

= 2*22/7*63/2*63/2

=11*9*63

=6237 cm

=62.37m

Answer 2

❏ Solution:-

❚ For a Circle of diameter r ,

(1)Area is given by,

$\sf\longrightarrow \boxed{Area=\pi r{}^{2}}$

(2) Circumference is given by,

$\sf\longrightarrow\boxed{ Circumference=2\pi r=\pi d}$

❏ Question:-

Q) The diameter of Ravi bicycle tyre measure 63cm how far does the bicycle move when the wheel make one complete revolution ?

❏ Solution:-

❚ Given:- • Diameter (d)=63 cm

❚ To Find:- • Circumference=?

NOW, to find the distance covered by the cycle ,we have to find the circumference of the tyre,

$\sf\implies Circumference= \pi d$

$\sf\implies Circumference= \frac{22}{\cancel7} \times \cancel{63}$

$\sf\implies Circumference= (22\times 9)$

$\sf\implies Circumference= 198\:cm$

$\bf\therefore$ The wheel will move 198 cm=1.98 m in one revolution.
