So a circular pool will be in the shape of a cylinder. and the formula for finding the area of a cylinder is

. r=radius, h=height. If we put the numbers into the equation it is

.14 squared is 196 and 4*14= 56. So our equation is now

. 2*pi=6.28318530718 but let's round that to 6.283. So now our equation is much simpler 6.283(196)+6.283(56). Just multiply them. 1231.504+351.858= <span>
1583.362</span> is your final answer.
B. 24x+27. You multiply everything out and add the x's
Two supplementary angles are in the ratio 3:7. Find the angles ?
Let the two angles be 3x and 7x.
Supplementary angles add up to 180 degrees.
Therefore:
3x + 7x = 180
10x = 180
x = 18
3x = 3 * 18 = 54
7x = 7 * 18 = 126
