What is the sin of pi divided by 2?
sin (pi/2) = 1
What is pi r2 divided by 2 plus 80 times 50?
(pi*r2)/2 + 4000
What is the sin of pi divided by 6?
1/2
How can you find the area of a circle?
the area of a circle is pi times radius2. half a circle is pi times radius2 divided by 2.
What is area of a circle if circumference equals pi divided by 2?
Area of a circle is: pi times radius squared
Given the circumference of a circle what is the radius?
Circumference equals the diameter times pi. The diameter is 2 times radius. Radius equals Circumference divided by pi then divided by 2.
What is 2 pi divided by 2 pi?
1
What is the purpose of pi?
Pi is basically the relationship between the circumference and diameter of a circle. (c/d). If you divide the circumference by the diameter you will always get pi, since C=Pi times d (or 2 times pi times radius), so circumference (C) divided by diameter (D) is Pi.
What is the area of a semi-circle with a radius not r but r divided by 2?
The area of a circle is pi R2The area of 1/2 circle is 1/2 pi R2The 'R' of this half-circle is r/2, so its area is 1/2 pi (r/2)2 = 1/8 pi r2
What is the cosine of 3 pi divided by 4?
0.75
What is the radius of a circle if the circumference is 15.7?
Circumference is 2 times pi (3.1415........) times the radiusRadius is circumference divided by (2 x 3.1415)= 2.387Another answer:2*pi*radius = 15.7radius = 15.7/2*piradius = 2.498732607 units
What formula is pi r divided by 2?
I don't think there is one. There is pi*r*2 (* meaning times by), which is the area of a circle. Other wise I'm not sure.
What is 4 times 3 divided by 15000 times 6 divided by 2 times 5 divided by 16000000 plus 1 equals what?
1.00000000075
How do you find the area of a circle knowing only its circumference?
If you know a circle's area, you can easily determine its radius using equation (1). Once you determine r, then plug it into equation (2). Pi = 3.14. (1) A = [Pi]r2 (2) C = 2[Pi]r Hint: Equation (1) can be rewritten r = SQRT(A/Pi)
What is the value of the product 4 divided by 3 times 3 divided by 2 times 2 divided by 1?
0.444444
How do you find the area and perimeter of a half circle?
Find the area and perimeter of the full circle, then throw away 1/2 of each.Perimeter (circumference) of a circle = (pi) times (diameter).For a half circle, it's (1/2 pi) times (diameter)Area of a circle = (pi) times (radius)2For a half circle, it's (1/2 pi) times (radius)2
What is 2 pi radius?
Pi is the circumference of (distance around) a circle divided by its diameter (largest distance across). The radius is one-half of the diameter. 2 pi radius means two times pi times the radius or 2 x pi x radius. You can multiply in any order so this is the same as 2 x radius x pi. 2 x radius = diameter diameter x pi = circumference (distance around) 2 pi radius is the circumference of a circle
