For example, when r1 = 2, r2 = 1, h = 1

  1. To calculate C1, use the following formula: 2πr1. When you substitute r1 for its value, you get 2π(2), which equals 12.56637 m.
  2. To calculate C2, use the following formula: 2πr2. When you substitute r2 for its value, you get 2π(1), which equals 6.28319 m.
  3. To calculate t, use the following formula: r1 - r2. When you substitute r1 and r2 for their values, you get 2 - 1 = 1 m.
  4. To calculate L1, use the following formula: 2πr1h. When you substitute r1 and h for their values, you get 2π(2)(1), which equals 12.56637 m2.
  5. To calculate L2, use the following formula: 2πr2h. When you substitute r2 and h for their values, you get 2π(1)(1), which equals 6.28319 m2.
  6. To calculate A, use the following formula: π(r12 - r22). When you substitute r1 and r2 for their values, you get π(22 - 12), which equals 9.42478 m2.
  7. To calculate V1, use the following formula: πr12h. When you substitute r1 and h for their values, you get π(22)(1), which equals 12.56637 m3.
  8. To calculate V2, use the following formula: πr22h. When you substitute r2 and h for their values, you get π(12)(1), which equals 3.14159 m3.
  9. To calculate V, use the following formula: V1 - V2. When you substitute V1 and V2 for their values, you get 12.56637 - 3.14159, which equals 9.42478 m3.
