From the diagram, we can see that the radius of the cone is 8cm and the height of the cone is 15cm. We then just plug these numbers into the formula and simplify:
The volume of the cone is approximately 1005.3096 cm^3. With 3 sig figs, this is 1010 cm^3.
Answer:
The surface area of the triangular prism is
Step-by-step explanation:
Step 1: Finding the two area of two triangles
Area of the triangle =
Area of the triangle =
Area of the triangle = 26.117
Area of 2 triangles =
Step 2: Finding the area of the side rectangles
Area of the rectangle =
Area of the rectangle 1 = = 23.56
Area of the rectangle 2 = = 32.3
Area of the rectangle 3 = = 37.24
Step 3: surface area of the triangular prism.
Surface area of the triangular prism = 52.234 + 23.56 + 32.3 + 37.24
Surface area of the triangular prism = 145.334
