Answer:
1733.28
Step-by-step explanation:
we want to find the surface area of the cylinder
We are given:
diameter = 12in
height = 40in
formula to find surface area of a cylinder: SA = 2πr^2 + 2πrh (where h = height and r = radius)
in order to find the SA of a cylinder we need to know the radius
we are given that the diameter is 12
we can acquire the measure of the radius by dividing the diameter by 2 ( this is because the radius is equal to half of the diameter )
so r = 12/2 = 6
now to find the surface area,
we simply plug in the values of the radius and height into the SA of a cylinder formula
SA = 2πr^2 + 2πrh
r = 6
h = 40
( note it says use 3.14 for π )
substitute values
SA = 2(3.14)(6)^2 + 2(3.14)(6)(40)
if you plug this into a calculator you get that the surface area is 1,733.28
Answer:
2/3 gallons
Step-by-step explanation:
Given data
We have the following data
1/2 gallons is the same as 0.5 gallons
hence 0.5 gallons will cover 3/4 of his deck
x gallons will cover 1 of his deck
cross multiply we have
3/4*x = 0.5*1 gallons
3x/4= 0.5
3x= 2
divide both sides by 3
x= 2/3
Hence 2/3 gallons will cover the entire deck
