Pls help btw this is for a friend

Answer 1

Answer:

$3\frac{3}{10}$

Step-by-step explanation:

Given: diameter = $6\frac{3}{5}$

This is a mixed number.

We have to convert mixed numbers to improper fractions.

$6*\frac{5}{5}+\frac{3}{5} \\ \frac{30}{5}+\frac{3}{5}=\frac{33}{5}$

diameter = 33/5

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

$\frac{33}{5} /2=\frac{33}{5}*\frac{1}{2} =\frac{33}{10}$

Improper fraction back to a mixed number.

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

$\frac{33}{10}=3\frac{3}{10}$

$r = 3\frac{3}{10}$
