The truck's tank is a stainless steel cylinder. Find the surface area of the tank. Round your answer to the nearest hundredth.
50 (height)ft
radius = 4 ft

2513.27

Step-by-step explanation:

Right cylinder

Solve for volume

V=πr^2h V=π4^2*50 = V≈2513.27

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
