A=pi times R squared If the radius is 5, the area is 25pi
The area of a circle of radius r is pi*r*r
It is 78.5 square units.

Well, honey, the area of a circle with a 5 km radius is about 78.54 square km. So, if you're looking to throw a party in that space, you've got plenty of room to work with. Just make sure to invite me!
The area of a circle, if the radius is 5 cm, is: 78.54 cm2
The area of a circle (to the nearest hundredth) with a 5-unit radius is: 78.54 square units.

A=pi times R squared If the radius is 5, the area is 25pi
For a radius of 5 centimeters the area are 78.53981633974483 square centimeters.
The area of a circle of radius r is pi*r*r
About 78.54m2
Just like any other circle, the area of that one is (pi) times (the square of the radius).
Area = 78.5 cm2
if you double the radius (or diameter) , you get four times the area. area of a circle = pi * radius squared
The area of a circle with radius 5 is 25 pi. Concentric circles with radius 3 and 4 have areas of 9 pi and 16 pi. The concentric circle with radius four consumes the circle with radius 3. 25 pi minus 16 pi leaves 9 pi of the circle with radius 5 left over. 16 pi is slightly over three-fifths of the circle with radius 5.
