SURFACE AREA OF A Cone

Click the link below and observe what happens when You move the sliders. Elaborate! 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? Name the parts of a cone! Fill in the blanks on the picture of its net. Hints:1. It is not a cape, it is.... + how it is called in a cone2. The name of the straight line(s) of 1.)3. The name of the round shape and how it is called in a cone. base sector slant height circle lateral surface area 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. Click on the link below, move the sliders, observe and describe the relationship among the cone's radius, true height, and slant height! Look at this picture and write the equation for the slant height. 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 Calculate the surface area of a cone that has a base radius of 15 cm and sector of 5375 cm2. l = 114.12 cmh = 113.13 cmB = 225πcm2A =5600 π 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 Calculate the surface area! Draw and label a 3D model of a cone that has a diameter of 8 cm and a central angle of the lateral surface 72o. Find the radius, the height, the slant height and Exact Surface Area of the cone above. Draw close representation of the net of the cone above. A right cone has a height of 16 m and a Base of 144π 2.Draw and label a 3D model of the cone.Draw close representation of the net of the cone. Find the radius, the slant height, Exact Surface Area and the central angle of the lateral surface of the cone above.
