0Area required = 130/360 x 16 pi ie 18.15 sq m

The formula is: (130/360)*pi*42 in square meters

Area of a circle = pi*radius squared

The area of a circle of radius 21 is 1386

The radius of a circle with the area of 36 is 3.385

The area of a circle if the radius is 9m 254.5m2

The area of a circle with a radius of 14.4 is 651.4

The radius of a circle when the area is 96 is 5.528

The area of a circle with a radius of 2m is: 12.566 m2

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 7yd is 153.9yd2

A circle with a radius of 10m has an area of 314.16 m2

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

For a circle or radius r, the area is given by: area = {pi}r2 (ie pi times the radius squared)

When you try to figure out an area of a circle, you square the radius, then multiply it by pi to get the area of a circle. A radius square is radius x radius, or radius squared.

The area of a circle with a radius of 14 is: 615.75 square units.

The area of a circle with a radius of 100 is: 31,420 square units.

The AREA of a circle that has a radius of 40ft is 5026.54825 square feet

The area of a circle with a radius of 4 is: 50.27 square units.

3850m is the area of the a circle whose radius of 7meaters

Area of circle = pi*(radius)2

In a circle, the area of the circle is pi times the radius squared

To increase the area of a circle you must increase the radius.

Area of a circle in square cm = pi*radius squared
