Given
Diameter of cylinder = 7 m
Radius of cylinder (r)= 7/2m
Height of cylinder (h)= 20 m
Length of Cuboid (l) = 22 m
Breadth of Cuboid (b) =14 m
Find out
We have to find the the height of the platform (Cuboid).
Solution
Let Height of Cuboid = H
Volume of Cuboid = Volume of Cylinder
l × b × H = πr2h
22 × 14 × h = π × (7/2)2 × 20
H =
\(\begin{array}{l}\frac{\frac{22}{7}\times\frac{7}{2}\times\frac{7}{2}\times 20}{22\times14}\end{array} \)
H = 5/2 m
H = 2.5 m
Answer
Hence, the rheight of the platform = 2.5 m
