Question

Draw the different 3D shapes figures with formula for their C.S.A,T.S.A and volume

Answer 1

3D shapes : cylinder , cone , hemisphere , cuboid

Step-by-step explanation:

cylinder:

curved surface area of the cylinder = $2\pi rh$

Total surface area of the cylinder= $2\pi r(r+h)$

volume of cylinder = $\pi r^2h$

cone :

curved surface area of the cone =  $\pi rl$

Total surface area of the cone= $\pi r(l+r)$

volume of cone = $\frac{1}{3}\pi r^2h$

hemisphere:

curved surface area of the hemisphere= $2\pi r^2$

Total surface area of the hemisphere= $3\pi r^2$

volume of hemisphere = $\frac{2}{3}\pi r^3$

cuboid :

lateral surface area of the cuboid  = $2h(l+b)$

Total surface area of the cuboid = $2(lb+bh+hl)$

volume of cuboid = $l \times b \times h$
