Answer 1

Answer:

increase 9 times

hope its help u

Answer 2

Answer:

D) increases 9 times

Step-by-step explanation:

radius of circle = r

area of circle = πr² =A1

( if radius is increased 3 time )

radius of new circle = 3r

Area of new circle = π(3r)²

= π9r²

=9(A1)

Hence, d) area increases 9 times
