Answer:
A = 588 in^2
Step-by-step explanation:
"a" is actually the sign for Pi, which is a set ratio of 3.14159.
The instructions say to use just 3 for Pi in this question though.
A = (3)14^2)
A = (3)(14)(14)
c. 12
PA² = (BC + PB) × PB => tangent-secant theorem
PA = 8
PB = 4
BC = ?
Substitute
8² = (BC + 4) × 4
64 = 4BC + 16
64 - 16 = 4BC + 16 - 16
48 = 4BC
48/4 = 4BC/4
12 = BC
BC = 12
