How do you find the volume of a cone?
(pi)xr2xh÷3 (area of base x height) (pi) times radius squared times height divided by three
Can you find the volume of a cone?
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
What is pi times 3 divided by 3?

What is the volume of a cone with a base area of 11.5 pi cm squared and the height of 20 cm?
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.
What is the surface area of a cylinder with a radius of 8 and a length of 20?
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)
