Answer 3

how do u find radius in this problem @gypsy1274

Answer 4

They gave you the diameter, I have you the relationship between the diameter and the radius. solve for radius.

Answer 5

do you do 15/2=7.5=radius?

Answer 6

Yes.

Answer 7

so 7.5 is the radius so 2pi7.5^2

Answer 8

?

Answer 9

circumference = \(\pi \times 2 \times r\)

Answer 10

so =353.43

Answer 11

not r squared just simple r
