How do you calculate the perimeter of a semi circle?
The perimater of a circle is the same as the circumference of a circle, but if it's only a half of a circle (semi-circle) you would use the formula 2*pi*r/2 If it's a quarter of a whole circle, or a fifth of a circle, then you would divide it by 4 or 5.
How many degressin a right angle?
A right angle is always formed by two perpendicular lines. These lines would split a circle into quarters. There are 360 degrees in a circle, so one quarter would be 90 degrees. A right angle is always 90 degrees.
What is the perimeter of a rectangle that is 20cm by 2cm which has a quarter circle of radius 11cm on one 20cm side running off the 2cm side using 3.14 for π?
Normally, the amount of the side of the rectangle below the quarter circle on it would expected to be calculated. However, the radius of the circle equals the amount that is subtracted, but in calculating the perimeter it has to be added back in again as it forms part of the perimeter. Thus the perimeter is the perimeter of the rectangle plus a quarter of the circumference of the circle. → perimeter = 2 × (20cm + 2 cm) + ¼ × 2 × π × 11 cm ≈ 44 cm + 3.14 × 11/2 = 61.27 cm.
How many lot in one quarter acre of land?
In the US, it depends on how the area is zoned. High-density zoning could allow for as many as three lots, but one or two lots would be more typical, since one-quarter of an acre would make a single lot about 110 feet by 100 feet.
Why is the circle city in Baghdad built in a circle?
Because if it were not, it would not be the circle city!
How would you circle one quarter?

How many degrees is two times a quarter of a rotation of a circle?
I'm guessing a quarter of a rotation of a circle would be 90 degrees (360/4) so two times would be.. 180? :)
What is a quarter turn in math?
A quarter of the way around a circle would be 90 degrees or pi/2 radians.
What is the name of the semi circle moon phase?
The semi-circle shape can be the 1st or 3rd quarter. Perhaps you would want to double check, but I believe that if the "flat" side of the shape is facing to the left, that is the 1st quarter; to the right - 3rd quarter.

How many pencils would it take to circle the earth?
The height of typical pencil is about 15cm. Laid end to end you would need 66,791,933 to circle the Earth at the equator.

What is the area of a quarter circle with radius 6 inches?
That would be 1/4 of the area of the entire circle. pi * r^2/4 (or πr2/4). Area of a circle = pi*62 = 113.0973355 or about 113 square inches, which, when divided by 4, gives you 28.25 square inches.

Does the word viruses have an apostrophe?
NO, if you typed "viruses'" (viruses with an apostrophe) it would mean "The viruses' (more than one virus's) something.
Why Pi should be replaced with tau?
Pi (3.14) should be replaced with tau because angles are measured easily in radians than in degrees. For an example, there are 2Pi radians in a circle. 2Pi is equal to one tau (6.28). Therefore, there are tau radians (360 degrees) in a circle. A semicircle would have half tau (180 degrees) and a quarter of a circle a quarter tau (90 degrees) and so forth. P.S. - Pi is a constant which references the circumference of a circle to its radius (2Pi radius; it will become tau radius).
