Answer:
4618.14 or 4618
Step-by-step explanation:
From T.S.A = 2rh + 2
where T.S.A = 1628
1628 = 2rh + 2
1628 = ( rh + ) 2
by dividing both side by 2
= rh +
259.10 = rh +
rh = 259.10 -
h = <u> </u>(1)
From Radius + Height = 37
r + h = 37 <u> </u>(2)
by substituting eqn 1 into 2
r + = 37
by multiplying r to both side
+ 259.10 -
= 37r
259.10 = 37r
r =
r = 7.00 ≅ 7
From Eqn 2
r + h = 37
7 + h = 37
h = 37 - 7
h = 30
so Volume of a cylinder =
V = *
* 30
V = 4618.14 ≅ 4618
