Suppose awater tank in the shape of a right circular

cylinder is thirty feetlong and eight feet in diameter. How much

sheet metal was used inits construction?

Answer:854.08 ft^2 was used for its construction.

Step-by-step explanation:

To determine the amount of sheet metal that would be used in the construction of water tank, we we determine its total surface area. The formula for determining the total surface area of a right circular cylinder is expressed as

Total surface area = 2πr^2 + 2πrh

Where

r represents the radius of the cylinder

h represents the height of the cylinder.

π is a constant whose value is 3.14

From the information given,

h = 30 feet

diameter = 8 feet

Radius = diameter/2 = 8/2 = 4 feet.

Therefore,

The total surface area =

2 * 3.14 * 4^2 + 2 * 3.14 * 4 * 30

= 100.48 + 753.6 = 854.08 ft^2
