This circle is centered at the origin and the length of its radius is 3 over 2 What is the equation of the circle?
Since the circle is centered at the origin, the equation of the circle is x2 + y2 = r2. So we have: x2 + y2 = (3/2)2 x2 + y2 = 9/4
What fraction of the area of a circle of radius 5 lies between concentric circles of radius 3 and 4?
The area of a circle with radius 5 is 25 pi. Concentric circles with radius 3 and 4 have areas of 9 pi and 16 pi. The concentric circle with radius four consumes the circle with radius 3. 25 pi minus 16 pi leaves 9 pi of the circle with radius 5 left over. 16 pi is slightly over three-fifths of the circle with radius 5.
What is the circumference of a circle if the radius is two over three?
pi * (2/3) * 2 =~ 4.1887902047863909846168578443727
How would you shade the fraction 19 over 3?
Draw 6 circles 'cut' into 3 pieces and shade all of them. Draw one more circle 'cut' into 3 pieces. Shade only one diece in the last circle,
What is the radius of 7 over 2?
Seven over teo is a number (3 1/2 or 3.5) and has no radius. Only a circle has a radius.
