clearly the radius of the circle is 3.
So, what is pi * 3^2 ?
The point (3,0) lies on a circle with the center at the origin. What is the area of the circle to the nearest hundredth?
THANK YOU!

If the point, (3,0) lies on the center, clearly it has to be the radius because half the diamenter is the radius. If u don't believe try it out urself, im sure u will get ur answer
Radius is 3
Pi times 3^2 = 28.27 rounded
A = 28.27 rounded
Pi times 3^2 = 28.27 rounded
A = 28.27 rounded
The center is at the origin and the point (3,0) lies on the circle, so r=3
A=pie x r squared
A=pie x 3 squared
A=9 x pie
A= 28.27
A=pie x r squared
A=pie x 3 squared
A=9 x pie
A= 28.27
So then how do u know that the 3 is the radius....it doesn’t say it.
it suuuuuuuuuuuuuuuuuuuukkkkkkkkkkkkkkkkkkkkkkkkkkkkeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeddddddddddddddddddd
