Answer:
Decimal: 0.23
Fraction: 23/100
Percent: 23%
Step-by-step explanation:
In this case, one whole is 100. This is because there are 100 little squares in the one big square.
The amount of shaded squares is 23.
This can be represented as the fraction 23/100. 23/100 is the same as 23 being divided by 100. 23 divided by 100 is 0.23 (our decimal). To find a percent, move the decimal point to the right 2 times. Our percent is 23%.

Answer:
4618.14
or 4618
Step-by-step explanation:
From T.S.A = 2
rh + 2

where T.S.A = 1628
1628 = 2
rh + 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
