Answer:
The area is multiplied by 9.
Step-by-step explanation:
the area of a circle when the radius is tripled
Formula for the area of a circle is [tex]\pi r^2[/tex]
'r' is the radius of the circle
When the radius of the circle is tripled then radius becomes 3r
Plug in 3r for 'r' in the formula of area of circle
area of a circle= [tex]\pi r^2[/tex]
area of a circle when radius tripled = [tex]\pi (3r)^2[/tex]
= [tex]\pi *9r^2[/tex]
= [tex]9\pi r^2[/tex]
area of a circle when radius tripled = 9 * area of a circle
The area is multiplied by 9.
