Jawaban dan Penjelasan

Berikut ini adalah pilihan jawaban terbaik dari pertanyaan diatas.

no. 3

d = 14cm maka r = 14 :2 = 7cm

t = 18cm

volum = \pi \times r {}^{2} \times t \\ = \frac{22}{7} \times 7 {}^{2} \times 18 \\ = 2.772cm {}^{3} \\ \\ luas =2 \times \pi \times r(r + t) \\ = 2 \times \frac{22}{7} \times 7(7 + 18) \\ = 44 \times 25 \\ = 1.100cm {}^{2}

no. 4

volume = luas \: alas \: \times tinggi \\ = \frac{10 \times 12}{2} \times 30 \\ = 1.800cm {}^{3}

no. 5

volum = ( \frac{1}{2} \times \frac{4}{3} \times \pi \times r {}^{3} ) + ( \frac{1}{3} \times \pi \times r {}^{2} \times t) \\ = ( \frac{2}{3} \times \frac{22}{7} \times 7 {}^{3} ) + ( \frac{1}{3} \times \frac{22}{7} \times 7 {}^{2} \times 12) \\ = 718,67 + 616 \\ = 1.334,67cm {}^{3}
