Geometry- finding radius of a circle. please only answer if you actually know. it would help so much

D

Step-by-step explanation:

For a circle, the equation of the circumference is c = π * 2r (radius). Since in this case, the circumference is 15.3, that means π * 2r = 15.3. I'm going to assume that pi is 3.14 because the four answers aren't particularly close to each other. This means that 2r = approx. 4.872. If you then divide both sides by 2 you get r = approx. 2.436, which is closest to answer D.

unless if u could do my questions, if not i wouldn't want to

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
