Question

a bicycle wheel has a radius of 28 centimetre what is the circumference of the wheel​

Answer 1

★ANSWER :

Circumference of the wheel is 176 cm.

★ EXPLANATION :

•Given :-

• Radius of the wheel = 28 cm.

• To find :-

• Circumference of the wheel.

• Solution :-

Radius(r) of the wheel= 28 cm

We know,

Circumference of circle= 2πr

So,

Circumference of the wheel,

$\sf{2\times\:\frac{22}{7}\times\:28\:cm}$

$\sf\implies{2\times\:22\times\:4\:cm}$

$\sf\implies{176\: cm}$

Circumference of the wheel is 176 cm.

Answer 2

GIVEN:

Radius of the bicycle wheel = 28 centimetre

TO FIND:

Circumference of the wheel

SOLUTION:

We know that,

The circumference of wheel = 2πr

Where,

π value = 22/7

r = radius of the wheel

$= > 2 \times \frac{22}{7} \times 28 \\ \\ = > 2 \times 22 \times 4 \\ \\ = > 22 \times 8 \\ \\ = > 176 cm$

Therefore, the circumference of wheel is 176cm.
