The radius of a circle is half of its diameter. If the diameter is 18 cm, then the radius would be 18 cm divided by 2, which equals 9 cm. Thus, the radius is 9 cm.
radius = 18/2 = 9 cm
SA = 904.78 cm2
A cone with a base radius of 12 cm and a height of 18 cm has a volume of 2,714.34 cm3
Volume = pi*r2*h = 40715.04 cubic cm
18cm = 180mm
radius = 18/2 = 9 cm
Using 3.14 as Pi the area of circle is: 1017.36
1,017.9 cm2
9 cm (r = d/2)
SA = 904.78 cm2
The perimeter is pi*r + 2r = 92.6 cm
A cone with a base radius of 12 cm and a height of 18 cm has a volume of 2,714.34 cm3
The diameter is always double the radius so in this case, it is 18cm
The answer is 6.6
Volume = pi*r2*h = 40715.04 cubic cm
The area of a parallelogram with base 18cm and perpendicular height 18cm is 324 cm2
18cm = 180mm
