For this case you can use the following equation:
d = (2 2/5) h
Rewriting:
d = (2.4) h
Then, we have that the height is:
h = 22 1/4
Rewriting:
h = 22.25
Finally the diameter is:
d = (2.4) (22.25)
d = 53.4 feet
The volume of the cylinder is:
V = pi * ((d / 2) ^ 2) * (h)
V = (3.14) * ((53.4 / 2) ^ 2) * (22.25)
V = 49806.05985 feet ^ 3
Nearest hundreth:
V = 49806.06 feet ^ 3
Answer:
The volume of the cylinder is:
V = 49806.06 feet ^ 3
Sorry mate, I can help with 8.) and 9.)
8.) angle T=180-(21+35)
T=180-56
T=124
Angle V=124
Triangle TUV is an isosceles triangle therefore, it has two equal sides and two equal angles.
9.) Angle WSV=21 degree
Triangle TSV is an isosceles triangle therefore, it has two equal sides and two equal angles.
TSV=21+21=42 degree
Had to run, can’t do rest. Hopefully, this helped a bit. Good luck.
A) this is the simplified form

b)
7 = 3/4 (3) + c
28 = 9 + 4c
4c = - 19
c = - 19/4
y = 3/4x - 19/4
5 = 3/4x - 19/4
3/4x = 39/4
x = 13
75% = 3/4
3/4 of 180 = 135
