Circumference of cone formula
WebCone. A cone, usually referred to as a circular cone, is a 3D geometric figure that has a circular base and comes to a point outside the base. ... you get a flat lateral surface, or circular sector, as shown above. The arc of this sector is the circumference of the base, which is 2πr. The radius of this sector is s. Therefore, the area of the ... WebThen the areas of your sides are lw, wh, and lh (length, width, and height). Multiply these together, and you get l²w²h²= (lwh)²=V². So to get the volume of your figure, multiply your three areas together and take the square root. ( 4 votes) Show more comments.
