Answer 2

All geometrical formulas

________________

(a) Circle

♦surface area = π r²

♦ circumference = 2 π r

_______________

(b) Cylinder

✓Volume = π r² h

✓ surface area = 2πr ( h + r )

✓ Lateral area = 2πr h

✓ Base area = π r²

_______________

( c) cone

♠ Volume = 1/3 π r²h

♣ πr ( r + l)

→ l is the slant height = √(r²+h²)

♠ base area = πr²

♣ lateral area = πrl

_______________

( c) sphere

♪ volume = 4/3 π r³

♪ Circumference = 2πr

♪ surface area = 4πr²

_______________

( d) cube

✓ volume = side ³

✓ surface area = 6a²

_______________

(e) cuboid

✓ volume = length × width × height

✓ surface area = 2( lw + lh + wh)

(f) pyramid

♦ volume = 1/3 × πr²h

• Any pyramid

→ surface area = area of base + area of each lateral faces

•Regular pyramid

→ surface area = area of base + 1/2 p s

{ p is the perimeter and s is the slant height }
