Answer:
x= -21
Step-by-step explanation:
-1/3=7/x
-1x=21
-1x/-1=21/-1
x= -21
Given that the radius of the circle is 6 cm.
The central angle is 120°
We need to determine the length of AB.
<u>Length of AB:</u>
The length of AB can be determined using the formula,
Substituting 
and 
in the above formula, we get;
Simplifying the values, we get;
Substituting π = 3.14, we have;
Thus, the arc length of AB is 12.56 cm
Substitute -1 for the variable x.
f(-1) = 2(-1) - 2
f(-1) = -2 - 2
f(-1) = -4
Answer:
x² - 10
Step-by-step explanation:
The area of the shaded region is the total area subtracted by the area of the non-shaded region.
Total:
Square with side s = x.
The area of a square of side s is A = s².
So
At = s² = x²;
Non-shaded:
Rectangle, of base b = 2 and side s = 5.
The area of a rectangle with base b and side s is A = b*s.
So
Ans = b*s = 2*5 = 10
Shaded:
At = At - Ans = x² - 10
False because the shape may change but a circo could have the same volume as a ball. a box could have the same volume as a cylinder box
