The area of a square is the length of its side, squared. If a square lawn has area 338, then its side is sqrt(338) = 13sqrt2.

If the sprinkler covers all the way up to the corner of the lawn, we must use the Pythagorean theorem to calculate its radius. If the side of the square is 13sqrt2, then the diagonal of the entire square would be sqrt2*(side length) = sqrt2*13sqrt2 = 2*13 = 26 ft. Then the distance from the center to the corner would be half this diagonal, or 13 ft.

So the radius of the circle is 13 ft.

  110/17 = p/28

  p = 28(110/17) ≈ 181

There are about 181 deer in the woods.

Estimate the value of this expression by rounding each number to the nearest unit
Alina [70]
So rounding to the nearest unit means replacing the number and taking the closest integer it is to. For example 0.96 is 1, and 5.45 is 5. So doing this in this prob. is 1 × 10 × 5, or 50.
