Question

the height and radius are equal in length. if TSA of cylinder is 616CM. what is the height of cylinder.

Answer 1

then
2pieR[H+R]
44x2H^2/7 = 616
H2 =616X7/88
H = 7

Answer 2

$\huge \red { \boxed{ \boxed{ \mathsf{ \mid \ulcorner Answer : \urcorner \mid }}}}$

GIVEN :-

Radius (r) = height (h)

T.S.A of cylinder = 616 cm²

===========================================

TO FIND :-

Height of rectangle

============================================

SOLUTION :-

We have formula for area of cylinder :-

Area = 2πr(r + h)

{Put Values}

616 = 2 × h (h + h) × 22 / 7

616 = 2 ( 2h²) × 22/7

616 × 7 = 4h² × 22

4312 = 88h²

h² = 4312/88

h² = 49

h = √49

h = 7

•°• Height (radius) of cylinder is 7 cm
