Divide the radius by pi then times them
Are you looking for where they cross ? if so its (-1,2)
Answer:
the answer is B
Step-by-step explanation:
im smart
So r+c=42
c=4+r
subsitute c=4+r for r in r+c=42
r+4+r=42
add like terms
2r+4=42
subtract 4 from both sides
2r=38
divide both sides by 2
r=19
rob=19
subsitute r=19 for r in c=4+r
c=19+4
carly=23
