A cylindrical tank has a diameter of 7.9 feet and height of 2.1 feet. Water is being poured into the tank at a rate of 3.7 cubic feet per minute. How long will it take to fill the tank

it will take 27.8 minutes to fill the tank

Step-by-step explanation:

The formula for determining the volume of a cylinder is expressed as

Volume = πr²h

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,

Diameter = 7.9 ft

Radius = diameter/ = 7.9/2 = 3.95 ft

Therefore,

Volume = 3.14 × 3.95² × 2.1

Volume = 102.9 ft³

If Water is being poured into the tank at a rate of 3.7 cubic feet per minute, the time it will take to fill the tank is

102.9/3.7 = 27.8 minutes

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.
