The area of the circle is given as:

Plugging the value of the radius we have that:

Therefore the area in terms of pi is:
Answer:
$1.20
Step-by-step explanation:
9.20 x 4 = 36.8
7.60 x 5 = 38
38 - 36.8 = 1.20
Answer: The area of Charlene's rhombus is nine times smaller than the area of Jerry's rhombus.
Step-by-step explanation:
I will assume that the exercise says "
times the base and height of Jerry’s rhombus".
The area of a rhombus can be calculated with the following formula:

Where "b" is the length of the base and "a" is the altitude or the height.
Then, you can calculate the area using the formula shown above.
Therefore, you get:
1. Jerry's rhombus:

2. Charlene's rhombus:

Dividing the area calculated, you get:

Therefore, you can conclude that the area of Charlene's rhombus is nine times smaller than the area of Jerry's rhombus.
Answer:
a. 6
b. 7
c. (b) Kira's
why? b. it has the large sample size
Step-by-step explanation:
X= -b over 2a = --6 over 2×1=3
y=3²-6(3)-7=-16
vertex is (3,-16)
axis of symmetry is 3
