Hey dear friend

Given-:
Height of A Well=7m
Volume of a well=26.62m³

To find-:
Diameter of a well= ?

Solution-:

=>Volume of a Well= πr²h
=>26.62m³= 22/7*r²*7
=>26.62/22=r²
=>1.21=r²
=>r=✓1.21
=>r=1.1

So, the diameter=2r
Diameter=2*1.1
Diameter=2.2m

So, the diameter of a well=2.2m

Volume of cylinder = πr²h


Form equation and solve for r:

Given that the height is 7m and the volume is 26.62 m³

26.62 = πr²(7)

r² = 26.62 ÷ 7π

r² = 1.21

r = √1.21

r = 1.1 m


Find Diameter:

Diameter = Radius x 2

Diameter = 1.1 x 2 = 2.2 m


Answer: The radius is 2.2 m
