The general equation for the area of a circle is π*r2, where r is the radius of the circle, and π is pi, which is approximately 3.14159. The diameter of a circle is how far it is from one side of the circle to the other, and the radius is how far it is the from edge to the center, thus the radius is half the diameter. Therefore the area is π*(92) ~ 254.47
area=basexheight=18x5=90
The Lateral Area of a cylinder with diameter of 12 cm and a height of 20 cm is equivalent to 0.075 square meter. Diameter of 12 cm is equals to 0.06 meter in radius and height of 20cm is equals to 0.2 meter
Circumference= 3.14 x Diameter Area of circle= 3.14 x diameter x diameter
Area = Pi(d/2)2 where d = diameter
Area of Circle = pi (radius)2 So , using this formula we can find the radius and also the diameter. Diameter = 2(radius)
area=basexheight=18x5=90
The Lateral Area of a cylinder with diameter of 12 cm and a height of 20 cm is equivalent to 0.075 square meter. Diameter of 12 cm is equals to 0.06 meter in radius and height of 20cm is equals to 0.2 meter
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
Total surface area including the two end pieces: (2*pi*radius2) + (pi*diameter*height) Area = 240*pi square inches
Diameter is 8.64444
Circumference= 3.14 x Diameter Area of circle= 3.14 x diameter x diameter
To find the diameter of a circle, you will either need to know the area or its circumference. If you know the area: diameter = 2 x squareroot(area / Pi) If you know the circumference diameter = circumference / Pi
I assume that you are referring to the area of a circle. You divide the diameter in half to find the radius and then you put it into the formula.
To convert diameter to area , you will need to divide the diameter by two so as to get the radius. The result you get, square it and them multiply it by 3.14 to find the area.
To find the volume, you need to find the area of the circular base, then multiply it by the height. The base is a circle, so use the equation A=pi*radius^2 (radius squared). So Area (A) = pi *1.3^2 (Use 1.3 since radius is half the diameter) Now multiply your answer for Area by the height (0.75), to give the volume of your cylinder.
A diameter is a line. A single line cannot enclose a space, and thus has no area.
Area = Pi(d/2)2 where d = diameter
