A cylindrical tank has a radius of 4.5 ft and an altitude of 14 ft. If a gallon of paint will cover 130 ft squared ft2 of surfa ce, how much paint in gallons is needed to put two coats of paint on the entire surface of the tank? Aswer: To put two coats of paint on the entire surface of the tank, ______ full gallons of pain are needed.
2 answers:
You would need 11 cans of paint to cover it twice
Surface area = 2*area circle + area lateral side circle area = pi * 4.5 * 4.5 = 63.585 circle circumference = 2*pi*4.5 = 28.26 lateral area = 28.26 * 14 =395.64 surface area = 63.585*2 + 395.64 = 522.81 522.81/130 = 4.02gallons 2*4.02= 8.04 <span>To put two coats of paint on the entire surface of the tank, EIGHT full gallons of pain are needed.</span>

Answer:
y=-9
Step-by-step explanation:
slope intercept form: y=mx+b, m being the slope
y=6 times -3
since there isn't a y intercept, you can't really put it in standard form unless I missed a step.
y= -9
Answer:
Length = 27.2
Width = 6.8
Step-by-step explanation:
P = L+L+W+W
68 = 4(L+L)+W+W
68 = 4(x+x)+x+x
68 = 4x+4x+x+x
68 = 10x
x = 6.8
L = 4x
L = 27.2
W = x
W = 6.8
68 = 27.2+27.2+6.8+6.8
68 = 68
