Answer:

1.)A cylinder's volume is π r² h, and its surface area is 2π r h + 2π r².

2.)A sphere is a perfectly round geometrical 3-dimensional object. ... A sphere with radius r has a volume of 4 3 π r 3 \frac{4}{3} \pi r^3 34πr3 and a surface area of 4 π r 2 4 \pi r^2 4πr2.

3.)Surface area of a cone = πrs + πr2. Volume of a cone = 1/3πr2h.

4.)So for a cube, the formulas for volume and surface area are V=s3 V = s 3 and S=6s2 S = 6 s 2.

5.)The volume of a triangular prism is equal to the product of the triangular base area and the height of the prism. Volume = Area of the Base × Height of prism. Since, the base is in triangular shape, therefore, Area = ½ b h.

6.)What Is the Formula for the Volume and Surface Area of a Triangular Pyramid? The volume of a triangular pyramid can be found by 1/3 × Base Area × Height.

7.)Surface area: SA = 6s(a + h) *Volume: V = 3ash
