Answer:

  412.7 square feet

Step-by-step explanation:

A circle of circumference 72 ft will have a radius given by ...

  C = 2πr

  (72 ft) = 2(3.14)r

  r = (72 ft)/(6.28) ≈ 11.465 ft

The area of a circle with that radius is ...

  A = πr² = 3.14(11.465 ft)² ≈ 412.7 ft²

Sirgeo can enclose a circular area of about 412.7 square feet with 72 feet of fence.

What is the volume of the following rectangular prism?
blondinia [14]

Answer:

14/3

Step-by-step explanation:

To find the volume of a rectangular prism, you need to multiply the area of the base by the length or height of the prism. In this case, the area of the base is 3 1/3, and the length of the prism is 1 2/5 units. Multiplying these together you get:

3\dfrac{1}{3}\cdot 1\dfrac{2}{5}=\dfrac{10}{3}\cdot \dfrac{7}{5}=\dfrac{70}{15}=\dfrac{14}{3} cubic units. Hope this helps!

The length would be 16 ft on both sides.. The width would be 7 ft, I think since a wall is forming one side, and he 40 ft, so in order to make the other three side the maximum would be 39 ft, so I think you get it now. This is just my guess... I'm only in sixth grade :/
