The volume, v, of a cone is 1/3*pi*r2*h
so r2 = 3*v/(pi*h) = 3*1232/(pi*24) = 154/pi
then r = 7.0014.
Area of curved surface = pi*r*(r2+h2)0.5 = pi*7.0014*(154/pi+576)0.5
= pi*7.0014*25.0004 = 549.9 sq cm
The calculations become much simpler if you use the approximation pi = 22/7
r2 = 154/pi = 154/(22/7) = 154*7/22 = 49 so that r = 7
Then, r2+h2 = 49+242 = 252
So area = pi*7*25 = (22/7)*7*25 = 22*25 = 550 sq cm
If the radius is r cm and the height is h cm, then Volume = pi*r^2*h cm^3 and Surface area = 2*pi*r(r+h) cm^2
pi * radius2 * height
The volume is 47.12 cubic meters.
Surface Area and Volume of a CylinderVolume= 1/3(PI) (radius)2 Surface Area= 2(PI)r2+2(PI)(radius)(height) or 2πrh+2πr2Pi x r² x h
A cylinder with a radius of 3 meters and a height of 5 meters has a volume of 141.37 cubic meters.
A circular cone has a height of 17mm and slant height of 21mm.find (1) the volume (2) the total surface area, of the cone the total surface area, of the cone Help me please Thank
Curved surface area = pi*radius*slant length Voume in cubic cm = 1/3*pi*radius2*height

Volume of a cone in cubic units = 1/3*pi*radius squared*height
The total curved surface area is 888.5 cm2
First we must find the radius: Curved surface area of the cylinder excluding the two end pieces = 88 cm2 2*pi*radius*14 = 88 Divide both sides by 2*pi*14 radius = 1.000402499 cm Volume = pi*1.0004024992*14 Volume = 44.01770994 cubic cm
Volume = (Pi/4) * diameter2 * height or volume = Pi * radius2 * height
The volume of a circular cylinder varies directly with the height of the cylinder and with the square of the cylinder's radius If the height is halved and the radius is doubled then the volume will be increased.
The answer is squareroot r2+h2 squareroot radiusxradius + heightxheight
The volume of a right circular cone with a radius of 4mm and a height of 6mm equals 140.88mm3
As a cylinder is a three dimensional object with volume = {pi}r2h (with r the radius of the circular end and h to height of the cylinder), I presume you mean its surface area: There are 2 circular ends with area {pi}r2 each. Plus the curved surface which has one dimension the height of the cylinder, the other the circumference of the circular end, so its area is 2{pi}r x h. So the total surface area of a cylinder = 2 x {pi}r2 + 2{pi}r x h = 2{pi}r(r + h).
volume is length x base x height and surface area is volume divided by height~
