Question

An arc of 1 inch is part of a circle of radius 1 inch. What is the measure of the central angle that forms this arc?



57.3
B. 60
C. 90
D. 14.6

Answer 1

can u sketch it out?

Answer 2

No need to sketch this. Start by finding out the circumference.
\[2 \times \pi\times 1 \implies 2\pi\]

Answer 3

Also remember that an arc is directly proportionate with the central angle. That can result in a proportion that looks like this:\[2\pi :360 = 1:x \]

Answer 4

so its 2*3.14 dividedby 360/x

Answer 5

ahh dnt get it
