Question:
a. A = (2πr)(r)
b. A = (2πr)(2r)
c. 
d. 
Answer:
The correct option is 
Step-by-step explanation:
The formula for the area, A of a parallelogram = base, b × height, h
Therefore, since the base dimension is approximately half the perimeter of a circle, we have;
Base, b = 2·π·r × 1/2
Where the height of the parallelogram, as shown in the diagram is approximately the radius of the circle, we have;
Height, h = r
Therefore, the approximate area, A of the parallelogram is given by the following relation;
A = b × h = 2·π·r × 1/2 × r Which is the same as A =
.
Answer:
the first one to solve for x is x=22-y
the first one to solve for y is y=22-x
the second one to solve for x is x=6+y
the second one to solve for y is y=-6+x
Step-by-step explanation:
in the first two you had to subtract y from both sides of the equation
the second one you had to add y to both sides of the equation to solve for x
but to solve for y you have to move all terms that dont contain y to the right side and solve
Answer:
the last one
Step-by-step explanation:
Theos number is -2/5
4x + 20 = 10
-20 -20
4x = -10
x = -4/10
x = -2/5
