The lateral surface area is 565.49cm2
answer me
r = 4.74835 cm
A cone with a base radius of 12 cm and a height of 18 cm has a volume of 2,714.34 cm3
pi*2.82*12 = 295.5610368 or about 296 cubic cm
Area of cylinder = circumference x height = 2r x Pi x h = 12cm x Pi x 10cm = 120 x Pi square centimetres = 376.9911 cm2 (to nearest 4th decimal)
The lateral surface area of a right circular cone with a radius of 12cm and a slant height of 20cm is approximately 754cm2
answer me
r = 4.74835 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 circumference of circle with radius 12cm is 75.4cm
452 cm3 (this assumes you mean 12 cm vertical height, not slant height). If the slant height is 12 cm then the volume changes to 392 cm3.
The radius of the sector with an angle of 27 degrees and arc of 12cm is: 25.46 cm
The diameter is twice the radius and so it is 24cm
2(pi)r=2X3.14X3cm=18.85cm to four significant figures
pi*2.82*12 = 295.5610368 or about 296 cubic cm
Area of cylinder = circumference x height = 2r x Pi x h = 12cm x Pi x 10cm = 120 x Pi square centimetres = 376.9911 cm2 (to nearest 4th decimal)
between 11.98 and 11.99 cm depending on how you calculate. 12cm is a good answer.
