Question

Pls help btw this is for a friend

Answer 1

`3(3)/(10)`

Explanation:

Given: diameter =
`6(3)/(5)`

This is a mixed number.

We have to convert mixed numbers to improper fractions.

`6*(5)/(5)+(3)/(5) \\ (30)/(5)+(3)/(5)=(33)/(5)`

diameter = 33/5

Now diameter = 2*radius so we divide 2 by diameter to get our radius.

`(33)/(5) /2=(33)/(5)*(1)/(2) =(33)/(10)`

Improper fraction back to a mixed number.

10 can go into 33, 3 times so left with a 3 remainder.

`(33)/(10)=3(3)/(10)`
