Answer:

75. 36 ft²

Explanation:

The volume of the cylinder can be calculated as:

base * height

the formula of base is:

πr²

find the radius by finding half the diameter: 4 ÷ 2 = 2 ft

π* 2² = 12.56 ft²

Then we calculate for the volume

12.56 * 6 = 75. 36 ft²

dont take my word for it but,

The volume of a cylinder can be calculated using the formula:

V = x * r^2 * h

Where:

V is the volume of the cylinder

x is the value of pi (3.14 in this case)

r is the radius of the cylinder (half the diameter, so 2 feet in this case)

h is the height of the cylinder

Plugging in the values from the problem, we get:

V = 3.14 * 2^2 * 6

= 3.14 * 4 * 6

= 75.36 cubic feet

So the volume of the rainwater collection tank is 75.36 cubic feet. The answer is therefore 75.36 cubic feet (Option B).
