Tolong hitungin luas permukaan dan volumenya, thanks
5dregensleyerjawaban soal A luas = 4 x π x r² = 4 x 3,14 x 12 x 12 = 3,14 x 576 = 1808,64 cm² volum = 4/3 x π x r³ = 4/3 x 3,14 x 12 x 12 x 12 = 3,14 x 16 x 144 = 7234,56 cm³
jawaban soal B luas = 4 x π x r² = 4 x 3,14 x 5 x 5 = 3,14 x 100 = 314 cm² volum = 4/3 x π x r³ = 4/3 x 3,14 x 5 x 5 x 5 = 314/3 x 5 = 523,34 cm³
jawaban soal C luas = 4 x π x r² = 4 x 3,14 x 6 x6 = 452,16 cm² volum = 4/3 x π x r³ = 4/3 x 3,14 x 6 x6 x6 = 8 x 3,14 x 36 = 904,32 cm³
luas = 4 x π x r²
= 4 x 3,14 x 12 x 12
= 3,14 x 576
= 1808,64 cm²
volum = 4/3 x π x r³
= 4/3 x 3,14 x 12 x 12 x 12
= 3,14 x 16 x 144
= 7234,56 cm³
jawaban soal B
luas = 4 x π x r²
= 4 x 3,14 x 5 x 5
= 3,14 x 100
= 314 cm²
volum = 4/3 x π x r³
= 4/3 x 3,14 x 5 x 5 x 5
= 314/3 x 5
= 523,34 cm³
jawaban soal C
luas = 4 x π x r²
= 4 x 3,14 x 6 x6
= 452,16 cm²
volum = 4/3 x π x r³
= 4/3 x 3,14 x 6 x6 x6
= 8 x 3,14 x 36
= 904,32 cm³
