Answer:
part A: 7.75 ft, part B: 48.69 ft
Explanation:
given a circle with diameter, D, 15.5 feet as shown below (<em>attached drawing</em>)
part A
radius, r = D/2
= 15.5/2
= 7.75 feet
= 7.75 (to the nearest hundredth)
part B
Circumference, C = 2πr
C = 2 × 22/7 × 7.75
C = 48.6947 feet
C = 48.69 (to the nearest hundredth)
note:
if you have 1234.5678, then
1 is Thousand
2 is Hundred
3 is Tens
4 is Unit
after the decimal, we have
5 is Tenth
6 is Hundredth (which is required in this question)
7 is thousandth
8 is Ten thousand etc
