I'm guessing a quarter of a rotation of a circle would be 90 degrees (360/4) so two times would be.. 180? :)
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.
6 times
4
Because 2 times the radius is equal to the diameter of the circle
3.1416 times. This figure is normally known as pi.
180 degrees
The answer is 210 degrees.
90 degrees * * * * * No! 1 rotation = 360 degrees so 21/4 rotations = 2.25*360 = 810 degrees
90 degrees
210 degrees
210 degrees
I think it's 275
210 degrees
There are 360 degrees in a full rotation. Taken 45 at a time you can do it 8 times.
7/3 x 90 = 210 degrees.
A full rotation of a circle is equal to 360 degrees. Area of a circle is: pi times radius squared.
ans:convert to decimal, or use fraction to combine result:get calculator out:2+(1/3) = 7/3 or 2.3333now, how many degrees in a quarter of a rotation?there are 360 in one rotation, therefore there are 90 degrees in 1/4 rotation!so we want to know (7/3).(90) = 210 degrees
