Answer:
13 glue sticks cost $25.22.
Step-by-step explanation:
4 blue sticks cost $7.76, this means that one glue stick costs
$7.76/4 = $1.94.
Let be the cost of the glue sticks, and
be the number of glue sticks; then
We can use this equation to find the cost of 13 glue sticks; we just put into our equation and it gives:
So 13 glue sticks cost $25.22.
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 = .
