A cone with height 8cm and radius 15cm has a volume of 1884.96cm3
A cone with a base radius of 5 units and a height of 15 units has a volume of 392.7 cubic units.
Volume is 335.1 units3
The volume is 1,900 units3
I can confirm that the answer is 251.33
Volume = 1/3*pi*42*15 = 251.327 cubic units
Volume = 1/3*pi*72*15 = 245pi cubic m
The surface area of a right cone with a radius of 8 and a slant height of 15 is: 377 units squared.
There is nothing in the question which indicates any sort of relationship between the first cone and the second. Consequently, the question has no sensible answer.
A cone with a 30ft height and a 15ft radius has a total surface area of approximately 2,287.44 square feet.
Volume is 3817 units3
The volume is 3,817 units3
