Question

v=π(R×R-r×r)h if R=2.6 r=2.3 π=22/7 v=115.5 then value of h is​

Answer 1

Step-by-step explanation:

v=π(R×R-r×r)h

115.5=22/7(2.6×2.6-2.3×2.3)h

h=[115.5×(7)/(22×2.6×2.6-2.3×2.3)]

h=[808.5/(22×1.47)]

h=[808.5/(32.34)]

h=25.015 and h=25.016 (approximately)

Answer 2

Answer:

v = π (R × R - r × r) h

115.5 = 22 ( 2.6 × 2.6 - 2.3 × 2.3) h

7

115.5 × 7 = (6.76 - 5.29) × h

22

808.5 = 1.47 × h

22

h = 808.5

22×1.47

h = 808.5

32.34

h = 25

The value of h is 25.
