Volume of a cone = 1/3*pi*radius2*height
Radius = 9pi/2pi = 4.5 cm
Height using Pythagoras = 6 cm
Volume = 1/3*pi*4.52*6 = 127.235 cm3 rounded to 3 decimal places

What is the slant length and perpendicular height of a cone whose radius is 5.25 cm with an entire surface area of 230.79 square cm showing work and taking pi as 3.14?
First find the slant length using the following formula:- Formula: (pi*radius2)+(pi*radius*slant length) = entiresurface area So: (3.14*5.252)+(3.14*5.25*slant length) = 230.79 Dividing all terms by 3.14*5.25: 5.25+slant length = 14 Subtract 5.25 from both sides: slant length = 8.75 Use Pythagoras to find height: 8.752-5.252 = 49 and sq rt is 7 Therefore: slant length = 8.75 cm and perpendicular height = 7 cm
