How do you divide a circle into 20 equal parts?
Well, sweetheart, to divide a circle into 20 equal parts, you simply start by drawing a vertical line through the center, then draw another line at 18 degrees from the first line, and keep going at 18-degree intervals until you've got yourself 20 equal slices of that circle. Easy as pie... or should I say, easy as circle?
What is the area of a circle if it has a diameter which is 18 feet long?
The area of a circle is equal to πr2 where π (pi) is equal to approximately 3.142 and r represents the radius of the circle. Because the question gives you the diameter and not the radius you have to use the measurement of the diameter to calculate the radius. Remember that the radius is equal to half the diameter. So if the diameter is equal to 18 feet, then the radius of this particular circle is equal to 9 feet. Plugging this into our equation for area we get: area = π(92) area = 3.142(81) area = about 254.5 ft2 (don't forget that the answer is in squared feet not just feet)
