jari2 = diameter/2
= 20/2
v= π r².t
= 22/7 . 10².25
=3,14 ×100×25
= 7.850 cm³
35. menghitung luas permukaan kerucut.
rumus L= luas alas kerucut + luas selimut
L= nr (r+s)
s²= r²+t²
=7²+24²
= 49+576
=625
s=√625
s=25
Luas permukaan kerucut = πr (s+r)
=3.14×7( 25+7)
=704 cm²
33. panjang kawat yg di perlukan ntk 5 balok.
= 4( 24+15+6)
=4×45
= 180
di tanya untuk membuat 5 krgka blok..
jd= 5×180
=900 cm.. :)
