Area of the circle: pi*152 = 706.858 square mm to 3 decimal places
Area = pi*152 square mm
The diameter of any circle is twice the radius. Since the radius of this circle is 15mm, the diameter is 15mm*2=30mm. 30mm is also 3cm.
The area of a circle with a diameter of 9.4 m is: 69.4 m2
The area of a circle is the radius square times pi. pi is equal to around 3.14159 Area = (3.14159)(302) = 2827.431mm
If the area of a circle is 8pi, its diameter is: 5.657 units.
Area = pi*152 square mm
The diameter of any circle is twice the radius. Since the radius of this circle is 15mm, the diameter is 15mm*2=30mm. 30mm is also 3cm.
The radius of the circle is half the diameter of the circle. 30mm radius would mean 60mm diameter or 6cm.
radius = 60/2 = 30mm
The radius is half the diameter 15mm because the raduis is half the diameter so 30mm divided by 2mm it would be 15mm
The diameter of a circle with an area of 37.68 is 6.92
The area of a circle with the diameter of 3m is 7.069 m2
The area of a circle with diameter of 4.9 is 75.43 units2
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
The area of a circle with a diameter of 9.4 m is: 69.4 m2
The area of a circle is the radius square times pi. pi is equal to around 3.14159 Area = (3.14159)(302) = 2827.431mm
Not clear which area you want. The surface area of the cylinder can only be determined if you give the length of the cylinder as well as its diameter. As you don't give this I conclude you want the area of the ends only. Each end will be the difference between the area of the 100 mm circle and the 30 mm circle. 100 mm diameter area = 7855 sq mm. 30 mm diameter area = 707 sq mm. Therefore area of end = 7148 sq mm, and you have two ends so total = 14296 sq mm
