Question 4
Step 1. Find radius
D = 2r
r = D/2
r = 35.2/2 = 17.6 cm
Step 2. Find area
A = πr²
A = π(17.6)²
A = 309.76π ≈ 973.14 cm²
Question 5
Step 1. Find radius
C = 2πr
r = C/2π
r = 100/2π = 50/π ≈ 15.92 m
Step 2. Find area
A = πr²
A = π(50/π)²
A = π(2500/π²)
A = 2500/π ≈ 795.77 m²
i think these are right i hope this helped if not im sorry
