The Smith family has bought an above ground
pool. The manufacture
recommends that it be filled
to within 1 foot of the rim.
What is the volume of the
water at this height.
37. (V=TTr?h) (use 3.14 for TT)
a. 7536 cubic feet
b. 6280 cubic feet
c. 1570 cubic feet
d. 1884 cubic feet

b. 6280 cubic feet

Step-by-step explanation:

Volume:

The volume of the prism, which has a cylindrical base, with radius r and height h, is given by:

Radius:

The radius is 20, so

The manufacture  recommends that it be filled  to within 1 foot of the rim.

Height of 6 - 1 = 5, so

Then

So the volume is 6280 cubic feet, and the correct answer is given by option b.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
