As an ordinary light bulb will illuminate the whole pool, not just a circle you must be thinking of a spotlight bulb. The answer will depend on how tightly focused the spotlight is.
The circumference of a circle when the diameter is 30 is: 94.25
A circle with a diameter of 1 metre has an area of pi/4 square metres.
-- The distance around the circle is 6feet 3.4inches. -- The area of the circle is 3.142 square feet.
A 56-inch diameter circle has an area of about 17.06 square feet.
Pi is the ratio between the circumference of a circle and its diameter. The Sun is also round - like a circle.
Measure the distance from top left corner of square (or top right) to the bottom right corner of square( or bottom left) to get the diameter of the circle. Then calculate the circumference from that figure.
The cord of a circle that contains the center of that circle is a diameter of that circle.
You do a diameter circle!!
If you mean the diameter of a circle with area pi, then the diameter is 2. If you mean the diameter of a circle with circumference pi, then the diameter is 2. If you mean the diameter of a circle with diameter pi, then the diameter is pi. If you mean the diameter of a circle with radius pi, then the diameter is 2pi.
A circle with a diameter of 28 is a circle.
The diameter of a circle is twice the radius.The diameter of a circle is twice the radius.The diameter of a circle is twice the radius.The diameter of a circle is twice the radius.
What do you mean by "height" if you are not referring to the diameter? The diameter is the distance from one side of the circle to another, crossing its center. Due to the definition of what is a circle, all diameters have the same length, whether it be from left to right, from top to bottom, or at any other angle.
Diameter of a circle = circumference/pi Diameter of a circle = 2*radius
Diameter of a circle = 2*radius Diameter of a circle = circumference/pi
The radius of a circle is half the diameter so if the radius of a circle is r, then the diameter is 2r.
The diameter of a circle is twice its radius
The diameter of a circle is simply twice the radius of the circle. The radius is a line that starts from the center of the circle to the circumference of the circle. The diameter is a line that passes through the circle. diameter=2xradius
