What fraction of a pie graph is 30 degrees?
Since a complete circle is 360 degrees, a 30-degree part of a circle is 30/360, or 1/12, of the pie.
What does 11.98 round up to?
12.0 if you want 3 sig-figs, or 12 if you only want 2.
Sine of 10 degrees x 12 equals?
Sin(10)*12 = 12*sin(10) = 12*0.1736 = 2.0838, approx.
How do you know if the pitch of a roof is 10 or 12?
A 12/12 is 45 degrees. If you set a 45 degree piece of wood on the roof it should be level.
Why does sin theta squared plus cos theta squared equal 1?
Sin2(theta) + cos2(theta) = 1 for the same reason that the sides of a right triangle squared equal the hypotenuse squared - The pythagorean theorem.In the unit circle (origin = (0,0), radius = 1), an angle theta is the angle made by some arbitrary ray drawn from the origin at an angle relative to the x axis. The point of that ray that intersects with the circle is the point (x,y).Sin(theta) is defined as x, and cos(theta) is defined as y. These are primary trigonometric identities, which link trigonometry with geometry.Since the points (0,0) (x,0) (x,y) (0,x) describe a right triangle, with (0,x) (0,0) (x,0) being the right angle, then x2 + y2 = 12, or sin2(theta) + cos2(theta) = 1.If this is not clear, draw a circle around the origin, draw a line from the center to an arbitrary point on the circle, and draw the x and y perpendiculars of that point to each axis. You will see a right triangle. X is sine, Y is cosine, and 1 is hypotenuse. It does not matter if X and/or Y is negative - the squaring will make it positive - and the pythagorean theorem should be visible.
What is the diameter of a 12 inch round circle?
diameter = circumference/pi = 12/pi inches
What is the circumference of a 12 inch round circle for the area?
well the formula is 2 pie r
What is the circumference of a circle that has a 12 inch diameter?
If the diameter of a circle is 12 inches the circumference is: 37.7 inches (diameter x Pi = circumference).
What is the circumference and diameter of 12 inch circle?
Circumference = 37.7 inches Diameter = 12 inches
What is the circumference of a 12 inch round circle?
Diameter = 12 inches, Circumference = 12*(pi) = approx. 37.699 Radius = 12 inches, Circumference = 2*12*(pi) = 24*(pi) = approx. 75.398 inches If the author has actually measured the outside of the circle (i.e. the perimeter of a dinner plate), that is the circumference! Problem solved.
What is the Circumference of a 12 foot 3 inch circle?
Circumference of a circle = 2*pi*radius or pi*diameter
If circle diameter is 12 what is circumference?
A 12-inch diameter circle has a circumference of: 37.7
What is the circumference of a circle with a 38 inch diameter?
12 inch diameter(also 6 inch radius).
Area of a circle with a 12 inch circumference?
The circumference of a circle is given by Circumference = pi x diameter. The area of a circle is given by Area = pi/4 x diameter2. Thus for a circle with circumference c = 12 in. The area will equal a = 11.459 in2.
What is the circumference of a circle with a 12-inch diameter?
If the diameter of a circle is 12 inches the circumference is: 37.7 inches (diameter x Pi = circumference).Circumference of a circle is pi x diameter, pi has a value of 3.1415, can you proceed from here, you can do it, try it, Good luck!
What is the diameter of a circle with a circumference of 38 inches?
12 inch diameter(also 6 inch radius).
How many 12 inch long blocks do you need to make a circle of 25 feet?
Circumference of a 25 feet circle = pie x diameter x 12 942.477 inch 1 feet = 12 inch so i converted into inch as i am having the other component in inch No of 12 inch long blocks = circumference /12 so total 78 pieces will be required to make a circle of dia 25 feet
