How do you divide a circle into 3 parts using only a confectionery ruler with no markings?
Draw a diameter on the circle from A to B and mark the midpoint, C (center of the circle). Mark the midpoint, D, of one of those radii (halfway between center and edge). Draw a perpendicular line to the diameter from D to the two edges of the circle, E and F. Draw radii from E to C and F to C. Lines AC, EC, and FC mark the three equal parts of a circle.
How do you find the radius of a circle in C?
The following code example will prompt the user to provide the circumference of the circle, then print the diameter, radius, and area.Code Example:#include #define fPI 3.141593F int main(void) { float fCircumference = 0.0; float fDiameter = 0.0; float fRadius = 0.0; float fArea = 0.0; printf("Enter the circumference of the circle: "); scanf("%f", &fCircumference); fDiameter = fCircumference / fPI; fRadius = fDiameter / 2; /* fCircumference / (fPI * 2) */ fArea = (fRadius * fRadius) * fPI; /* (fRadius 'squared') * fPI */ printf( "The circles diameter is: %f\n" "The circles radius is: %f\n" "The circles area is: %f\n", fDiameter, fRadius, fArea ); return 0; }
How many yards are in a 50 yard radius circle?
There is a circular pond whose diameter is 50 yards long, f you walk around this pond, how many yards do you walk?
How should the diameter measurement called french be abbreviated?
FR or F is the common abbreviation for the diameter measurement French
What letter is used as a mathematical symbol in geometry?
Some examples: a for area, b for breadth, c for circle or curve, d for diameter or depth or dimension, f for foci, l for length or line, m for modulus (= slope), r for radius, v for volume, w for width, x for horizontal coordinate, y for vertical coordinate, z for third orthogonal coordinate in 3-d geometry. and finally, pi for the ratio of the circumference of a circle to its diameter.
