Surface Area of a Cone

Click again on the link below and observe what happens when You move the sliders. What can you see when the "Net" slider is far on the left?And what do you see when the "Net" slider is far on the right? A cone is a three-dimensional geometric shape bounded by a circle and a curved plane. The circle is called a base of a cone, a curved plane is its sector and VT is called a slant. If S is the center of a base of a cone then VS is the axis of a cone. V is called the apex or the vertex.If the axis of a cone is perpendicular to its base, then the cone is right. Match the formulas for Area! Calculate the surface area of a cone that has a base radius of 9 cm and slant height of 15 cm. h = 12 cmB = 81π cm2A = 216π cm2 What is true for a cone that has a base radius of 6 cm and surface area of 116.5 π cm2? r = 36 cm l = 12 cm h = 12 cm B = 36 cm2 all of the above
