This cylindrical fish tank has a height of 36 inches and a a diameter of 30 inches what is the volume of the fish tank

First, you'll need to find the area of the base of the cylinder. Since the fish tank is a cylinder, its base is a circle, and you'll use *r^2.

r=(1/2)d = (1/2)30 = 15 inches
*15^2 = *225 (We'll worry about multiplying by pi later; for now, this is good enough).

Then, to find the volume, you just multiply by the height of the fish tank.
*225*36 = *8100 = 25446.9005

The answer, then, is 25446.9005 cubic inches (or just 8100 cubic inches)

Answer:

$4034.40

step-by-step explanation:

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
