The expanded algorithm is given as follows:

4 x 57 = (4 x 50) + (4 x 7) = 200 + 28 = 228


The standard algorithm is given as follows:

\ \ \ \ \ \ {_2}\\{ \ \ \ \ \ \ 5 \ 7} \\ \times \ \ \ \ \ 4 \\ = \overline{\underline{2\ 2\ 8}}

A rotating lawn sprinkler sprays water in a circular area of grass, as shown in the picture. The diameter of the circular area o
ratelena [41]

Answer:

The area the sprinkler sprays with water is 201.06 square feet.

Step-by-step explanation:

Step 1; It is given that the diameter of the circular area of grass that the sprinkler sprays with water is 16 feet. The diameter of a circle is equal twice its radius. So we divide the diameter by 2 to get its radius.

Radius of the circle = Diameter of the circle / 2 = 16 feet / 2 = 8 feet.

Step 2; The area of any given circle is π times the square of the radius. The radius of this circle is equal to 8 feet.

Area of the circle = π × r² = 3.1415 × 8 feet = 201.06 square feet
