Question

What is the radius??? ​

Answer 1

Step-by-step explanation:

circumference of a circle exceeds the diameter by 18..

circumference of circle is 2πr

diameter is d=2r

circumference exceeds diameter by 18

2πr=d+18

2πr=2r+18

2r(π-1)=18

r(π-1)=9

π=22/7

π-1=22/7-1=15/7

r(15/7)=9

r=63/15

mark me as brainliest and follow mr

Answer 2

Answer:42/5

Step-by-step explanation:

2πr-2r=18

2r(π-1)=18

r(22-7)/7=9

r=63/15=21/5
