Answer:
A. 31.4 in.
Step-by-step explanation:
Formula for the circumference:
C = dπ (d = 2r)
Therefore:
C = 10π
C = 10 · 3.14
C = 31.4 in.
The answer would be -105. If you multiply 7 x -15 it would give you -105 and then you would have to divide -105 by 7 and its equal to -15.
Answer:
c. 12
Step-by-step explanation:
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
(-4.25 + 2.5)/2 = -1.75/2 = -0.875
C is correct
54 because i got that a b and dc equal 6 and ad and bc equal 9
