9) A cow is tethered with a rope 20 ft long. What is the maximum area the cow can graze?

If the rope is 20 ft long, then the maximum area the cow can graze is:

r^2 square feet.

is approximately 3.14, so that means we have: 3.14(20^2) = 1256 ft squared.

Thus, the maximum area that the cow can graze is 1256 ft squared.

Let me know if this helps!

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
