Nomer 33 volum = tbung + krucut = ( π x r² x t) + ( 1/3 x π x r² x t) = (22/7 x 7 x7 x10) +( 1/3 x 22/7 x 7 x 7 x 6) = ( 22 x 70) + ( 22 x 14) = 1540 + 308 = 1848 cm³ jawaban C
nomer 34 luas permukaan Lp = La + Lstabung + 1/2Lpbola = ( π x r² ) + ( 2 x π x r x t) + ( 2 x π x r²) = ( 22/7 x 7 x 7) + ( 22/7 x 7 x 25) + ( 2 x 22/7 x 7 x 7) = ( 22 x 7) + ( 22 x 25) ( 44 x 7) = 154 + 550 + 308 = 1012 cm² bonus mas .. udah bener ngitungnya
volum = tbung + krucut
= ( π x r² x t) + ( 1/3 x π x r² x t)
= (22/7 x 7 x7 x10) +( 1/3 x 22/7 x 7 x 7 x 6)
= ( 22 x 70) + ( 22 x 14)
= 1540 + 308
= 1848 cm³
jawaban C
nomer 34
luas permukaan
Lp = La + Lstabung + 1/2Lpbola
= ( π x r² ) + ( 2 x π x r x t) + ( 2 x π x r²)
= ( 22/7 x 7 x 7) + ( 22/7 x 7 x 25) + ( 2 x 22/7 x 7 x 7)
= ( 22 x 7) + ( 22 x 25) ( 44 x 7)
= 154 + 550 + 308
= 1012 cm²
