Question

Diketahui sebuqh tabung denagn volume 5338 cm³ dan tingginya 17 cm .carilah diameter tabung itu (# : 3‚14)

tolong ya

Answer 1

VTabung = Phixrxrxt
5338 = 3,14xrxrx17
5338/(3,14x17)= rxr
100 = rxr
10 = r

diameter = 2xr = 2x10 = 20 cm

Answer 2

V = (1/4)πd² x t
5338 = (1/4) x 3,14 x d² x 17
d² = (5338 x 4)/(3,14 x 17)
= 21352 / 53,38
= 400
d = √400
= 20 cm
