What is area to the nearest tenth of a 120 degree sector of a circle with radius of 8 ft?
Area of whole circle = pi*r2 = 64*pi Area of Sector = Area of Whole Circle * Angle of Sector/Angle of Whole Circle = Area of Whole Circle * 120/360 = Area of Whole Circle / 3 = 64*pi/3 = 67.0 to the nearest tenth.
Is the Area of a circle and circumference of a circle have the same thing?
No,Circumference is like the perimiter and Area is the whole circle.
What is the central angle of a circle with a diameter of 20 inches and divided into 20 congruent sectors?
1
To find the area of a sector do you multiply the area of the circle by the measure of the arc determined by the sector?
No. Assuming the measure of the arc is in some units of length along the curve, you have to divide the result by the circumference of the circle. Basically, you need to multiply the area of the whole circle by the fraction of the whole circle that the sector accounts for.
What tells how many equal parts there are in the whole?
What Tells How Many Equal Parts There Are In The Whole? Well, I think the answer is... Denominator!!!!!!
How quarter circles equal a whole circle?
4.
How do you draw three and three-fourths?
Draw three whole circles and then draw a circle from which a quarter segment is cut out.
How many quarter circle equal a whole circle fraction?
Probably 4, but the question is somewhat garbled because of the way the language is used.
Two quarters of a circle is what decimal part of a whole circle?
1 quarter is equal to 25% or 0.25. 2 quarters are 50% or 0.50. So, two quarters is 0.50 or half of a whole circle. Hope that helped =)
If there is half a circle a quarter circle and an eighth of a circle how much more of the circle is needed to make it whole?
Half circle plus quarter circle is equal to three-fourths of a circle. Three-fourths of a circle plus one eighth of a circle is seven-eighths. You still need one more eighth to complete the circle.
Why is the equator called the great circles?
The reason they call the equator the great circle is because circles the whole earth in the middle.becase its the only line that runs in the centre of the earth and goes right arround . {nickstar}
What equal 360?
A whole circle.
How many quarter notes equal the duration of a whole note?
Four quarters is a whole. That's what the word "quarter" means.
What is 4 quarter note equal to?
A whole note.
Is a semi circle regular?
Yes it is. Pie = 3.14 or a half circle is 180 degree's where as a full circle is 360 degrees. I fly small aircraft an we always make incomplete circles, it used everyday in the world with engineers and mathematicians. Each quarter circle is 90 degrees, multiplied by 4 equals 360 degrees which is a whole circle. Hope this helped you. John U.
How do you find the perimeter of a quarter circle?
We know that the circumference of a circle is equal to the diameter times pi- or 3.14. With a quarter circle, we know the Radius- distance from the center point to the edge. Double that, and you have the diameter of a whole circle. Multiply that by pi, and you have the circumference of the whole circle- but since you have a quarter circle, divide that by 4. A 3 ft quarter- times 2= 6. 6x3.14= 18.84. divide THAT by 4=4.71. NOW add in the original radius for each of the two STRAIGHT sides- that is 3 x 2, or 6, PLUS the length of the curved part- 4.71, and you have 10.71 ft. So you have the length of the two straight sides, and the curving 3rd side combined.
What are circles?
Circles are a never ending object. They have no starting and no ending point. They have a center point and from the center to the edge of the circle is the same distance around the whole object.
