hypothesis is what you think will happen , a theory is a system of ideas to explain something. scientific law means a statement that is based on repeated experimental observations.

A hypothesis is a testable explanation, a theory is a well-substantiated explanation of phenomena, and a scientific law describes consistent patterns in nature. Hypotheses lead to theories, while laws serve as foundational principles. Each plays a crucial role in scientific understanding and the scientific method.

Jawaban:Ringkasan soal Masalah:Kita punya tangki berbentuk tabung dengan diameter 20 m dan tinggi 50 cm. Kita perlu menghitung luas permukaan tangki.caranya:1. Ubah satuan tinggi ke meter:Tinggi = 50 cm = 0.5 m2. Hitung jari-jari:Jari-jari (r) = Diameter / 2 = 20 m / 2 = 10 m3. Rumus luas permukaan tabung:Luas permukaan tabung = 2 × π × r × (r + tinggi)4. Masukkan nilai ke dalam rumus:Luas = 2 × π × 10 m × (10 m + 0.5 m)Luas = 2 × π × 10 m × 10.5 mLuas = 210π m²5. Hitung nilai numerik (gunakan π ≈ 3.14159):Luas ≈ 210 × 3.14159 m²Luas ≈ 659.734 m² maka, luas permukaan tangki tersebut adalah sekitar 659.734 meter persegi.

Penjelasan dengan langkah-langkah:Diameter = 20 m = 2000 cmr = 2000/2 = 1000 cmTinggi = 50 cmLuas = 2 x π x r x (r + t)Luas = 2 x 3.14 x 1000 x (1000 + 50)Luas = 6280 x 1050Luas = 6.594.000 cm²
