Diameter of the circle in the middle = 8 ft
Radius of the circle in the middle :
Thus, the radius of the circle in the middle = 4 ft
Area of the entire circle :
Thus, the area of the entire circle = 314 ft
Area of the circle in the middle :
Thus, the area of the circle in the middle = 50.24 ft
Area of the shaded portion :
= Total area of the figure - Area of the circle in middle
▪︎Therefore, the area of the shaded portion = <u>263.76 ft</u>
Answer:
110 is the correct answer...
Answer:
113.04square inches
Step-by-step explanation:
Answer:
-x²-2
Step-by-step explanation:
x² = the curve faces upwards
but
-x² the curve faces downwards.
also
the downward curve touches -2 on the y axis.
therefore gx = -x²-2
Ella has 0.5 lbs of sugar. 75% syrup
Percent of mass = 
Let the mass of solution is x
Given mass of solute = 0.5
percent of mass = 75
75 = 
75x = 0.5 * 100
75 x = 50
x = 0.67
Mass of solution = 0.67
Mass of water = mass of solution - mass of solute (sugar)
= 0.67 - 0.5 = 0.17
So 0.17lb of water is added with 0.5lb of sugar to get 0.67lb of solution.
