Question

Approximate the change in the volume of a right circular cylinder of fixed

radius r equals = 22 22 cm
when its height decreases from
h equals = 10 10 cm to h equals = 9.9 9.9 cm
​( Upper V (h )equals pi r squared h V(h)=πr2h​).

Answer 1

152.1 cm³

Explanation:

Change in Volume = πr²(h₁-h₂)

Where r = 22 cm

h₁ = 10 cm

h₂ = 9.9 cm

ΔV = π x (22)²x (10-9.9)

= π x 484‬ x 0.1

= 152.11

≈ 152.1 cm³
