What is the area of a circle when the radius is 15?
Area of a circle= (22/7)*r^2 where, r is the radius of the circle when r=15, area of the circle= 3.14*15*15 = 706.5 sq.units
What is the radius of a circle with a diameter of 15 cm?
The diameter of a circle is twice its radius. Thus the radius of a circle is half its diameter. → a circle with a diameter of 15 cm has a radius of 15/2 cm = 7.5 cm
What is a half angle?
A half angle is just what it sound like; it's half the measure of an angle. If you have an angle of 30 degrees, the half angle is 15 degrees. Simple and easy. Where it comes in handy is in construction of something like, say, an isosceles triangle inside a circle. If you have the two equal equal angles, you can find the third angle. Then you can construct it by drawing a chord across the circle through its diameter, then using the half angle to draw in one side. Repeating the process on the other side of the diameter will give you the other side of the triangle. By drawing in a chord connecting the points where the other two chords (drawn off the half angles on either side of the diameter) intersect the circle, you'll have completed the construction of the isosceles triangle.
What is the complement of the angle 75 degrees?
The complementary angle is 15 degrees. Complementary angles sum to 90 degrees, and 90 - 75 = 15.
15 percent out of 120?
15 percent of 120 is 18.
What is the angle for 15 percent of a circle?
.15 x 360 degrees = 54 degrees
How many degrees of the circle in a pie graph would the food category require if the percentage is 15 percent?
54 or 54.0
What is 15 percent to angle?
15% is a 54 degree angle.
How do you figure out angle measure of percent?
add 15 to it
What would the angle measure be to graph 15 red marbles out of 40 marbles?
135 degrees.
What is the angle of rotation for a point on a circle for drawing a regular 15-gon?
360/15 = 24 degrees.
How many degrees of the circle in a pie graph would the food category require if the percentage is 15?
54 or 54.0
What is one purpose of a circle graph?
circle graphs create a visual picture of a proportion compared to a whole. Sometimes it is easier to see 25% of this, 15 % of that, and 60 % of something in a circle graph than to hear someone verbally say it to you. Also, you can easily compare two percentages together.
What degree is a 15 percent ramp?
15%ramp is a rise of 15/100 = 0.15 slope angle is inverse tangent of this, or 8.53 degrees
What is the length of the minor arc if the angle in the circle is 90 and the radius of the circle is 15?
The total circumference of the circle is (2 pi R) = 30 pi.The central angle of 90° is 90/360 = 1/4 of the circle.The minor arc = 30 pi/4 = 23.562 (rounded)
How do you divide circle to 15 cm thank you?
There are various ways of measuring circles, since a circle has a radius, a diameter, and a circumference, so your question asking how to divide a circle to 15 cm is not as precisely stated as it might be. You can use a segment of a circumference to get 15 cm, by taking the appropriate wedge out of the circle, but even then, unless we know what the radius of the circle is, we cannot tell you what angle is needed to obtain the wedge you want, with a 15 cm circumference.
What kind of graph would best show the results of a survey of 144 people where 75 ride a bus 45 drive cars 15 carpools and 9 walk to work?
Circle graph/ pie chart
