Answer:
C = 56.52 in
A = 256.34 in²
Step-by-step explanation:
The figure is trying to show you that d=18 in, so r=9 in. The formulas for C and A are given, so you only need to put the numbers in the formula and do the arithmetic. Apparently, you're supposed to use 3.14 for π.
C = πd = (3.14)(18 in) = 56.52 in
A = πr² = (3.14)(9 in)² = (3.14)(81) in² = 254.34 in²
