Volume krucut 5.544cm,tinggi27cm.Diameter krucut adalah…cm

diketahui = v = 5.544 cm
= t = 27 cm
ditanya = diameter = ?
jawab. = v = 1/3 x phi x r x r x t
= 1/3 x 22/7 x r2 x 27
= 22 x r2 x 27/ 3 x 7
= 594 x r2 / 21
r2 = 5.544: 594/21
= 5.544 x 21/594
= 1164424 / 594
= 196
r = √196 = 14 cm
d = 14 x 2 = 28 cm

Vol kerucut= 1/3.phi.r².t
5544 =1/3.22/7.r².27
5544.21 =1.22.r².27
116,424=594 r²
116,424/594=r²
196=r²
√196=14
