7.3: Opp. ruimtefiguren

Stappenplan:

Schrijf de afzonderlijke grensvlakken op.
Bekijk welke dezelfde vorm hebben.
Bereken de oppervlakte van alle grensvlakken.
Denk aan de formules en maak eventueel schetsen.
Tel de oppervlaktes bij elkaar op.
Schrijf je conclusie op.

7.3: Opp. cilinder

o p p . b o v e n = π \cdot s t r a a l^{​ 2 ​ ​}

= π \cdot 1, 25^{​ 2 ​ ​}

= 4, 908 . . .

o p p . o n d e r = 4, 908 . . .

o p p . z i j = l \cdot b

= π \cdot 2, 5 \cdot 3

= 23, 561 . . .

o p p . c i l i n d e r =

4, 908 . . . + 4, 908 . . . + 23, 561 . . .

= 33, 4379 . . .

straal = 2,5 : 2 = 1,25 cm

Dus de opp. is ca. 33,4 cm2
