To find the area of a circle, you need to use the formula A=π⋅r2 , therefore the area A is π⋅62≈113 square inches. To find the circumference of a circle, you will use the formula C=2⋅π⋅r , therefore the circumference C is 2⋅π⋅6≈38 inches.
The relation of radius to diameter is , or . So 3.1415926 * 10 = 31.142″ if we round to thousandths of an inch. If the diameter is 8 inches, the radius is 4 inches.
Measure the radius of the circle. Multiply the radius by the radius. For example, if you have a 18 inch radius, you would multiply 18 inches by 18 inches to get 324 square inches. Multiply the step 2 result by 3.1415, an approximation of pi, to find the circular area.
64π square inchesA=πr2,where,r=8 inches given. So, A=π(8)2=64π square inches.
=78.5 square inches.
64 square inches9 inch = 64 square inches. 10 inch = 79 square inches. 12 inch = 113 square inches.
=78.5 square inches.
30.25π sqThe Area of the circle=πr2=π(112)2=30.25π sq.

If the length is, for instance, 10 inches, then compute as follows: 113 x 10 = 1,130 cubic inches.

78.5 square inches=78.5 square inches.
31.42cmSince the diameter is 10cm, we know that C = π x 10cm = 31.42cm (to 2 decimal places).
DefinitionsRadius is the length from the midpoint of the circle to the outer edge of the circle. Diameter is the full length of the circle running from the edge, through the midpoint, all the way to the other side. Now, circumference is the distance around the outside edge of this circle.
The formula for determining the total square feet in a circular area is: A = Pi x R2 (Area = Pi x R-squared). This formula may mean nothing to you so here's a explanation: To determine the total square footage in a circular area you will first need to determine the radius (R) of the circle.
If you know the radius of the circle, double it to get the diameter. The radius is the distance from the center of the circle to its edge. If the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm. If you know the circumference of the circle, divide it by π to get the diameter.

To a certain point, Doomsday is practically impervious to blunt force trauma of a punch from an opponent like Superman, seeing as he has been killed by Superman with his fists. However, Doomsday can be injured by exceptionally powerful blows though not be killed by normal means.
