10. Height of a cylinder is double the radius and its volume is 2156 m3. Find the dimensions of the cylinder​

Answer 1

$\huge\boxed{\fcolorbox{yellow}{orange}{☞✿ANSWER:-}}$

GIVEN :-

h = 2r

volume = 2156.

SOLUTION :-

Volume = π²h = (22/7)(r²)(2r) = 2156 m²

=> 2r³ = 2156 × 7/22

=> 2r³ = 98 × 7

=> r³ = 49 × 7

=> r³ = 7 × 7 × 7

Hence,

r = 7m.
