4 is the answer because you multiply
221.56, because in order to get the area of a circle, you must use this formula: area = (pi divided by 4) x diameter squared.
In this case, area = (3.14 / 4) x (16.8 x 16.8)
Answer:
the expression of this function is:

Step-by-step explanation:
This graph corresponds to an absolute value function, which as you can see has the minimum (vertex) at the point (1, -1) on the plane, and also that goes through the origin of coordinates (0, 0)
therefore, notice that from the point (0, 0) to (1, -1) there is a slope of "-1" which is going to characterize the steepness of the x- variable that resides inside the absolute value function. since the vertex has also moved from the characteristic (0, 0) in the function:

then we have to include a horizontal shift to the right in one unit (by subtracting 1 units from x), and a vertical shift downwards one unit (by subtracting 1 from the full absolute value expression) in order to shift the vertex to the position (1, -1):

Answer:
2500 ft²
Step-by-step explanation:
The missing area at lower right in the diagram has dimensions...
(4-2 1/4) by (3 - 1 3/4) by (1 1/4)
Then area of that "Missing" space is (1.75)(1.25)= 2.1875 . . . . square inches. The area of the enclosing rectangle is ... (4 in) (3 in) = 12 square inches the area in the diagram representing the store is... 12 in² -2.1875 in² = 9.8125 in²
_
Each square inch on that diagram represents an actual area of (1 in)×(1 in) → (16 ft)×(16 ft) = 265 ft²
Then the actual store area is....
9.8125(256 ft²) = 2512 ft²
Rounded to the nearest 50 ft², this is 2500 ft².
Hi!
From 4 p.m to 5:30 p.m. there is hour and a half, or 90 minutes.
Carolos played for 1/2 hour = 30 minutes.
Lisa played for 3/4 hour = 45 minutes.
Toni played = 90 - 45 - 30 = 15 minutes.
Hope this helps!
