Answer 1

Answer:

I think you need to find TOTAL SURFACE AREA and then multiply it by 110

Answer 2

Answer:

Thanks for for your question ;

Your answer is given below:

Step-by-step explanation:

Diameter = 7cm (given)

Radius = 7 upon 2

$2\pi \: r \: = circumference \: of \: wheel$

$= 2 \times \frac{22}{7} \times \frac{7}{2}$

=22cm

=0.22m

Diameter =110

Number of wheel rotate

$\frac{110}{0.22} = \frac{11000}{2}$

Answer is = 500 times
