Basil saw a very strange old bicycle at the museum. It had one very big wheel and one very small one. It was called an 'Ordinary' or a 'Penny Farthing'. At home Basil looked it up on the internet and found the big wheel could have a 52 inch diameter.

PART A - What is the circumference of the big wheel? Show how you figured it out.
Circumference = 163.3628
Formula for Circumference = π * diameter

PART B - How far would you travel in one turn of a big wheel? Give your answer in feet and inches. Show how you figured it out.​

You have part A correct. The circumference is pi times diameter.

The circumference is the distance around the wheel. If the wheel travels 1 full rotation, then the bike will move forward the exact amount of the circumference. So the bike will move forward approximately 163.3628 inches

Convert this to feet only

163.3628 inches = (163.3628 inches)*(1 ft/12 in)

163.3628 inches = (163.3628/12) feet

163.3628 inches = 13.6135667 feet, approximately

Now convert to feet+inches

13.6135667 feet = 13 feet + 0.6135667 feet

13.6135667 feet = 13 feet + (0.6135667 ft)*(12 in/1 ft)

13.6135667 feet = 13 feet + ( (0.6135667*12) in)

13.6135667 feet = 13 feet + 7.3628004 inches

13.6135667 feet = 13 feet + 7 inches ... rounding to nearest inch

13.6135667 feet = 13 feet, 7 inches

The bike would travel approximately 13 feet, 7 inches forward
