Question

a cylinder tank a cylindrical tank has a capacity of 3080

CM if its depth in 20 cm find its diameter

Answer 1

$\color{Magenta}{HOWDY}$

Given,
Capacity = 3080cm^3.
Height = 20cm.

Volume of Cylinder = π × r^2 × h
3080 = 22/7 × r^2 × 20
3080×7/22 = r^2 × 20
980 = r^2 × 20
980/20 = r^2
49 = r^2
√49 = r
7 = r

Hence,Diameter Will be
2 × radius = 2 ×7 = 14cm.
