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.

The hour hand of a clock completes one full circle every 12 hours. Therefore, in a 24-hour day, the hour hand covers a full circle twice. This is because the hour hand completes one full rotation from 12 o'clock to 12 o'clock in the morning and another full rotation from 12 o'clock to 12 o'clock at night.

Because 2 times the radius is equal to the diameter of the circle
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
7/3 x 90 = 210 degrees.
There are 360 degrees in a full rotation. Taken 45 at a time you can do it 8 times.
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
