The volume of a cylinder that is 30mm in diameter and 700mm high is 494,800.84mm3
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.
Area = pi*152 square mm
Area of the circle: pi*152 = 706.858 square mm to 3 decimal places
They are both the same because 30mm - 3cm
30mm*230mm = 6900 millimetres = 271.653543 inches
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.
radius = 60/2 = 30mm
A tensile rod in a mechanism is made from AISI 4140 OQT 1300 steel. It has a rectangular cross section , 30mm*20mm & a length of 700mm.It is to be
Area = pi*152 square mm
The radius is half the diameter 15mm because the raduis is half the diameter so 30mm divided by 2mm it would be 15mm
The radius of the circle is half the diameter of the circle. 30mm radius would mean 60mm diameter or 6cm.
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
About 3 centimeters (1.18 inches) in diameter... Radius 15mm Circumference of 9.42 cm, or 94.2 mm
King George II Halfpennies varied in size from 28 to 30mm in diameter.
Asking what the calibre is is the same as asking how many inches... In this case, the bore diameter would be 1.1811 cal.
Area of the circle: pi*152 = 706.858 square mm to 3 decimal places
Yes, a VERY large one known as the GAU-8. It fires a 30mm diameter bullet.
