The area of a regular pentagon with a radius of 7 is 10.1716. If the radius was 5, the area would be 7.26543.
Radius is x2 so area is x4.
The area of a circle whose radius is 19 centimeters is: 1,134 cm2
3850m is the area of the a circle whose radius of 7meaters
The radius of a circle whose area is 3.14 square centimeters is: 1 cm
Area of a regular polygon equals to the one half of the product of its perimeter with the apothem. So we have: A = (1/2)(a)(P) Since our polygon has 10 sides each with length 1.2, the perimeter is 12 910 x 1.2). Substitute 12 for the perimeter, and 1.85 for the apothem in the area formula: A = (1/2)(a)(P) A = (1/2)(1.85)(12) A = 11.1 Thus, the area of the decagon is 11.1.
The area is 314 cm2
A cylinder whose radius is 5 and height is 7 has a surface area of 377 units2
A cylinder whose radius is 6 and height is 14 has a surface area of 754 units2
For a radius of 5 centimeters the area are 78.53981633974483 square centimeters.
Area of a circle = pi (3.14) times the radius squared.
