The answer is 10 because its in the tens place
It would be 200+9+0.1+0.006.
The standard form of an equation of a line:
Ax + By = C
Therefore your answer is:
<h3>3x + 4y = 10</h3>
I am assuming that PC is a radius.
d = 2 * PC = 2 * 17 = 34
C = pi * d
C = pi * 34 = 34pi cm
if PC is a diameter, the change the 34 into 17.
