Answer:
The photo is not showing up
a is the answer as the only change is the gradient being halved,
b would be if it was -1/2 and c would be1/2 x+1/2
The answer is c because left side of number line is negative
Answer:
A =63.76512739 in^2
Step-by-step explanation:
The circumference is given by
C = 2 * pi * r
28.3 = 2* 3.14 *r
28.3 = 6.28r
Divide each side by 6.28
28.3/6.28 = 6.28r/ 6.28
4.506369427 =r
Now we need to find the area
A = pi r^2
A = 3.14 (4.506369427)^2
A =63.76512739 in^2
