Someone me? i have no idea what i'm doing

a mirror frame in the shape of an oval is shown below. the ends of the frame form semicircles:

which of the following is the perimeter of the inner edge of the frame?

343.56 inches
289.56 inches
258.78 inches
204.78 inches

i got 204. i have no idea what i'm doing wrong.

I got the same thing you did, which probably means that the question rounded the numbers differently. As little as I want to say this, since 204.78 in. is the closest, choose that.

Step-by-step explanation:

Calculations: (60 * 2) + (27*π): left, straight lines; right, circular parts

Multiply: 120 + 84.823

Add: 204.823 in.

company a

step-by-step explanation:

using the linear regression models , it is found that company a   pays about $14 more. but using the same regression (linear) company b pays about $10 more.

so company a pays more than b
