Answer:

$V=18,369\ in^3$

Step-by-step explanation:

step 1

Find the lateral surface of the cylinder (hot water tank)

The lateral area is given by the formula

$LA=2\pi r h$

we have

$r=13\ in\\h=75\ in$

substitute

$LA=2\pi (13)(75)$

$LA=1,950 \pi\ in^2$

step 2

Find the volume of fiberglass composite needed

Multiply the lateral area by the thick

$V=1,950 \pi (3)$

$V=5,850 \pi\ in^3$ -----> exact value

assume

$\pi=3.14$

$V=5,850(3.14)=18,369\ in^3$

the radius of a cylindrical water tank is 6.5ft, and its height is 16ft what is the volume of the tank?

dimulka [17.4K]

Answer:

Volume of cylindrical tank is 2122.64 cubed feet.

Step-by-step explanation:

It is given that:

Radius of cylindrical tank = 6.5 feet

Height of tank = 16 feet

Volume of tank = πr²h

Putting the values in the formula

Volume = 3.24 * (6.5)² * 16

Volume = 3.14 * 42.45 * 16

Volume = 2122.64 cubed feet.

Therefore,

Volume of cylindrical tank is 2122.64 cubed feet.
