Question

formula of area and volume of cone , sphere , hemisphere, cuboid,cube

Answer 1

⭕️volume of cube = side^3 or s×s×s
️Area of cube =A=6a^2

⭕️volume of cuboid = length x breadth x height or l×b×h
area of cuboid = SA=2lb+2bh+2hl

⭕️ volume of cylinder = π r^2h
area of cylinder =A=2πrh+2πr^2

⭕️volume of sphere = 4/3 π r^3
area of sphere =4πr^2

⭕️volume of hemisphere = 2/3 πr^3
area of hemisphere =4 π r^2
Half of this will be 2 π r^2

⭕️volume of cone = 1/3π x r^2 ×h
Total surface area of a cone = πr(l+r)
Curved surface area of a cone = πrl
Slant height, l=√h^2+r^2[whole root]

Answer 2

$\huge\mathfrak {Answer:-}$

Formulas:

T. S. A. of cone = π r l + π r 2

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

Volume of sphere = $\frac{4}{3} \pi \: r \: ^{3}$

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

Volume of cuboid = l × b × h

Volume of cube = $a^{3}$
