Justin's hot water tank quits working and the landlord purchases a new one. He is concerned about its size and whether or not it can hold about 700 gallons. To do so, it must have a volume of around 94 cubic feet.
What is the volume of a cylindrical water tank with a diameter of 4 and a height of 7 feet?

87.92 ft³

Step-by-step explanation:

The formula for the volume of a cylinder is πr² · h

1. Set up the equation

π2² · 7

2. Solve

(3.14)(4)(7) = 87.92

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
