Volume = pi*r2*h = 40715.04 cubic cm
A cone with a base radius of 12 cm and a height of 18 cm has a volume of 2,714.34 cm3
radius = 18/2 = 9 cm
area=basexheight=18x5=90
1/2b*h 180 cm^2
Volume = pi*r2*h = 40715.04 cubic cm
To calculate the surface area of a cylinder, you need to add the areas of the two bases (top and bottom) and the lateral surface area. The formula for the lateral surface area of a cylinder is 2πrh, where r is the radius and h is the height. Given the radius is 7cm (half of the diameter) and the height is 18cm, the lateral surface area is 2 * π * 7 * 18 = 252π cm². The total surface area is the sum of the lateral surface area and the areas of the two bases, which is 252π + 2(πr²) = 252π + 2(π*7²) = 252π + 98π = 350π cm², or approximately 1099.65 cm².
A cone with a base radius of 12 cm and a height of 18 cm has a volume of 2,714.34 cm3
The area of a parallelogram with base 18cm and perpendicular height 18cm is 324 cm2
The answer is 6.6
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)
180 cm2
The perimeter is pi*r + 2r = 92.6 cm
approximately 18cm or 7.2cm . this is upto my knowledge and experience
