(pi)xr2xh÷3 (area of base x height) (pi) times radius squared times height divided by three
Volume = Base x Height /3 Where base is the area of the base circle (pi*radius*radius) and Height is the perpendicular distance from the base to the apex of the cone
The formula for finding the volume of a cone is 1/3(pi)(r)(r)(h) where r is the radius and his the height, or in your case, 1/3(B)(h) where B is the area of the base and h is the height since part of the original formula is finding the base area [(pi)(r)(r)]. Plug your measurements into your calculator and you get 76 2/3 pi square cm, or 240.7 square cm.
The surface area is equal to the (circumference of the base) times (the length). Circumference of the base = (2 pi) times (radius) = 16 pi Surface area = (16 pi) times 20 = 320 pi = 1,005.310 square units (rounded to 3 decimal places)

No, the volume formula is not universal for all figures. Different shapes and objects have different formulas to calculate their volume based on their unique dimensions and properties. Each shape requires its own specific formula to accurately determine its volume.
I'm assuming you are asking about a cylinder. The volume of a cylinder is the area of the base times the height. The base is a circle so its area is pi*r^2. We get V=height*pi*radius*radius = 8*pi*3*3 = 72*pi which is about 226.195
Assuming you have a cylinder, the volume is area of the base multiplied by the height. The area of the base is the area of a circle of radius 3 (PI*radius^2 = PI*3^2 = 9*PI). The height is 5. The resulting volume would be 5*9*PI = 45*PI units^3. Did I just do your homework?
In base pi yes, it is 10 in base pi.
The volume is (54 pi) cubic units, about 169.65 cubic units V = pi x (r squared) x length The radius is 3, the area of the base is 9 pi (about 28.27) square units
Volume of a cone = 1/3 (pi) x (Radius of the base)2 x (Height)V = 1/3 (pi) R2 HMultiply each side of the formula by 3 :3 V = (pi) R2 HDivide each side by (pi) R2 :3 V/(pi) R2 = H
Volume of a cone = 1/3*pi*radius2*height measured in cubic units The area of the cone's base = pi*radius2 measured in square units
Volume = 1/3*pi*52*6 = 50*pi cubic m
Volume of a sphere = 4/3*pi*radius cubed
Depth of cone = Radius of semicircle = 28/2 cm = 14 cm Circumference of the base of cone = Arc of semicircle = 0.5*pi*28 = 14*pi cm Therefore radius of base = 14*pi/(2*pi) = 7 cm Capacity = 1/3*pi*r2*h where r is the radius of the base of the cone. = 1/3*pi*72*14 = 718 cm3
