multiply 2.5 by pi pi x 2.5
50 cm is the diameter.
The area of the circle is 490.87 cm2
78.54 yards
Radius = 1/2 of the diameter = 12.5 cm.
Formula for area of a circle is A = pr2r = 1/2d = 12.5cm, p = 3.142A = 3.142 x (12.5cm)2A = 490.9375cm2
The distance around any object is called its perimeter. The perimeter of a circle has a specific formula: 2(pi)r where pi is a number that is approximately 3.14 and r represents the circle's radius. In this case we are given the circle's diameter, however remember that the diameter of a circle equals two times its radius. So if: d = 50' and d = 2r Then r = 25' Now plus this radius into or equation to get: 2(3.14)(25) = 157' To get the distance around this circle 8 times, multiply the perimeter by 8: 157' * 8 = 1,256 feet
The circumference of a circle with a diameter of 25 is: 78.54
half times pi times 10....
The word perimeter means the distance around the outside of an object. The perimeter of a circle has a special name. We call it the circumference. The perimeter of this circle, or circumference, is 25 ft.
What is the approximate circumference of a circle that has a diameter of 25 yards
