Answer» ANSWER: ( a ) The circumference of one wheel = 44 cm ( b ) The total circumference of both wheel = 88cm Step-by-step explanation: The radius ( r ) of child's bicycle's wheel = 7cm ( a ) The circumference of one wheel = ? The Wheel is in the SHAPE of circle . Here, The formula used to find the circumference of wheel is the formula of circumference of circle. We know that , The circumference of the circle = 2 X PI X r Pi = 22/ 7 The circumference of the circle = 2 X 22/7 X 7 44 cm Hence, The circumference of the circle = 44CM . Therefore , The circumference of one wheel = 44 cm. ( b ) The circumference of both wheel = ? The circumference of one wheel = 44 cm The circumference of both wheel = 2 X 44 cm = 88 cm Therefore, The total circumference of both wheel = 88 cm

Answer»

( a ) The circumference of one wheel = 44 cm

( b ) The total circumference of both wheel = 88cm

Step-by-step explanation:

The radius ( r ) of child's bicycle's wheel = 7cm

( a ) The circumference of one wheel = ?

The Wheel is in the SHAPE of circle .

Here,

The formula used to find the circumference of wheel is the formula of circumference of circle.

We know that ,

The circumference of the circle = 2 X PI X r

Pi = 22/ 7

The circumference of the circle = 2 X 22/7 X 7

44 cm

Hence,

The circumference of the circle = 44CM .

Therefore ,

The circumference of one wheel = 44 cm.

( b ) The circumference of both wheel = ?

The circumference of one wheel = 44 cm

The circumference of both wheel = 2 X 44 cm

= 88 cm

Therefore,

The total circumference of both wheel = 88 cm
