A circle with a radius of 25 cm has an area of 1,963.5 square cm.
A circle with a radius of 12.5 feet (25/2) has an area of 490.87 square feet.
Area = (pi) (radius)2 = 25 pi = 78.54 square units (rounded)
The circumference of a circle if radius is 25 is about 157.1
Using 3.14 as Pi the area of circle is: 0
A circle with a radius of 25 cm has an area of 1,963.5 square cm.
Area = Pi(r)2 - A circle with a radius of 25 inches has an area of 1,963.5 square inches.
If you mean area of a circle with a radius of 25 cm then it is:- Area = pi*252 = 1963.495 square cm to 3 decimal places
yes
A circle with a radius of 12.5 feet (25/2) has an area of 490.87 square feet.
The formual for area is: A = πr2 so the area of circle A (assuming π=3.142) is 28.278cm2, and the area of circle B is 50.272cm2.Their combined area of 78.55cm2 is the area of circle C.The formula for radius is: square root of A/π78.55 ÷ 3.142 = 25, the square root of 25 is 5The radius of circle C is 5cmArea of Circle A = π32 = 9πArea of Circle B = π42 = 16πArea of Circle C = 9π + 16π = 25πLet r = radius of Circle C thenπr2 = 25π : r2 = 25 : r = 5.
1963.5 square units.
25/16
the formula for the area of a circle is pi r2 (pie are square). r is the radius. examples: radius of circle is 5. pi 52 = pi 25 = 78.53
The area of a circle with a 25-mile radius is about 1963.5 square miles. This calculation is based on the formula A = πr^2, where A is the area, π is approximately 3.14159, and r is the radius of the circle.
Area = (pi) (radius)2 = 25 pi = 78.54 square units (rounded)
The circumference of a circle if radius is 25 is about 157.1
