Main Answer:
To find out the area of the circle you must square the radius.
Here's the answer:
I took pie as 3.141592
Area = pie x radius squared
A = pie x 13.25 squared --> pie x (13.25 x 13.25)
A = 551.5457455
Don't forget to put the units on (e.g. mm, cm, etc) and round to whatever number of decimal places this question asks for.
Extra Info:
Circumference of a circle = pie x diameter
Area of a circle = pie x radius squared
C herry pie's d elicious --> C = pie x d
A pple pie's r 2 --> A = pie x r2
The area of a circle of radius 21 is 1386
Area of a circle = pi*radius squared
The area of a circle with a radius of 14.4 is 651.4
A circle with a radius of 135 units has an area of 57,255.53 square units.
If the area of a circle is 40.7 the radius is: about 3.6 (3.599)
The area of a circle if the radius is 9m 254.5m2
The radius of a circle with the area of 36 is 3.385

If you triple the radius of a circle, the area will increase by 9. Area is proportional to the square of the radius.
A= Area of the circle¶= Pi (About 3.14)r= Radius squared (Radius times radius)3.14 * Radius squared
