Area of 12 inches diameter cylinder = pi.r2 = pi*62 = 36*pi square inches (r = radius = 6 inches). Volume = area * height = 36*pi*36 = 1296*pi = 4071.5 cubic inches (to nearest 1st decimal). (pi = 3.14159 to nearest 5th decimal).
The volume of a cylinder with a diameter of 30 inches and 36 inches long is 25,446.9 cubic inches.
Area of the circle: pi*6 squared = 36*pi square inches
The volume of a cylinder 1.5 inches in diameter x 36 inches high is 63.62 cubic inches.
Area of circle: pi*6 squared = 36*pi square inches
diameter = 1' So radius = 6" So area = pi x 6² = 36 pi = approx 113.097 square inches
The formula used to find the area of a circle is (pi)r2.The radius is half the diameter, so the radius is 6 inches.The radius squared is 62, or 36 inches squared.Now, we multiply 36 by pi, or around 3.14.36 x 3.14= 113.04The area of the circle is approximately 113.04 inches squared.
The circumferecne of a circle with diameter d is pi*d So diameter = circumference / pi = 36/pi = 11.46 inches. Radius = diameter/2 = 5.73 inches.
The diameter is twice the radius in inches: 18*36 = 648 inches
About 1.92 times as much. (rounded) The so-called "light gathering power" varies in proportion to the area of the objective lens or mirror, which in turn varies as the square of its diameter. (36 inches/26 inches)2 = 1.9172 = about 2.83 dB
To find the diameter of a circle with a 36-inch circumference, you can use the formula C = πd, where C is the circumference, π is pi (approximately 3.14159), and d is the diameter. Plugging in the values, we get 36 = 3.14159 * d. Solving for d, we find that the diameter is approximately 11.46 inches.
An area cannot be 36 inches. However, assuming that the area was meant to be 36 SQUARE inches, then pi*r2 = 36 so r = sqrt(36/pi) = 3.39 inches.
