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.
A circle with a radius of 2.5 meters has an area of 19.63 square meters.
A circle with a radius of 3 meters has an area of 28.27 square meters.
A circle with a radius of 5 units has an area of 78.54 square units.
A circle with a radius of 9 feet has an area of 254.47 square feet.
A=Pi(r)2 - A circle with a radius of 1.6 centimetres has an area of 8.04 square centimetres.
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.
it couuld zero Area = Pi*r2 = Pi*36 = 113.0973 square centimetres (rounded).
If yo have the area of the circle, the square is irrelevant. Radius = sqrt(Area/pi)
To find the area of a circle based on its radius, multiply its radius squared by pi. Don't forget to square the radius before multiplying by pi, based on rules of BODMAS where you find powers of numbers before you multiply them.In this instance, (4.4 x 4.4) = 19.36. Multiplying this by pi gives us, accurate to two decimal places, 60.82. Don't forget to include the appropriate measurement. If the original measurement of the radius of the circle was in centimetres, then the area should be expressed in square centimetres. If the original measurement of the radius was in inches, then the area should be expressed in square inches.
Half the square root of the square radius equals the circle radius.
The radius of a circle with an area of 35 square inches is 3.34 inches.
The radius of a circle with an area of 17 Square meters is 2.33 meters.
If the area of a circle is 1519.76 square meters, the radius is 21.994422761843005 meters.
The radius of a circle, if the area is 22 square meters, is: 2.646 meters.
If a circle has area of 400 square units then its radius is: 11.25 units.
The radius of a circle with an area of 706.50 square inches is: 15 inches.
