Answer:
See below.
Step-by-step explanation:
The area of the circle is given by the formula:
From the circle, we can see that the diameter is 14. Thus, the radius must be 14 divided by 2 or 7.
We're also using 3.14 for π. Substitute:
Use a calculator:
And we're done!
1/2(x+6)=2x
1/2x + 3 = 2x
x + 6 = 4x
3x = 6
x = 2
5-2x+7x-h
5-2(2)+7(2) = h
h = 5 - 4 + 14
h = 1 + 14
h = 15
Step-by-step explanation:
the volume of a cylinder is as for any other regular 3D object :
ground area ×height
the ground area of a cylinder is a circle, so it is
pi×radius² × height
the radius is always half of the diameter (of the diameter is airways twice the radius).
radius = 6/2 = 3 ft.
the volume is then
pi × 3² × 9 = pi × 9 × 9 = pi × 81 ft³
so, the answer is 81pi ft³.
