Find the circumference of the inner and Outer circles shown in the adj

1.	Find the circumference of the inner and Outer circles shown in the adjoining figure ? take pi = 3.14I need the explanation for why we need to minus 10 from 19 to get the radius
Answer» Step-by-step explanation: for answer ,refer to the attachment the reason why we need to MINUS 10 from 19 to get the RADIUS of inner circle is simple ,that outer radius of circle is 19M and the diff between R and r is 10 m. so you can substitute the VALUES.... R is 19m and 10 m = R-r 10 m = 19m - r r = 19m - 10 m r = 9 m hope it will help u pls mark as brainliest...

Step-by-step explanation:

for answer ,refer to the attachment

the reason why we need to MINUS 10 from 19 to get the RADIUS of inner circle is simple ,that outer radius of circle is 19M and the diff between R and r is 10 m. so you can substitute the VALUES....

R is 19m and 10 m = R-r

10 m = 19m - r

r = 19m - 10 m

r = 9 m

hope it will help u
