Step-by-step explanation:

Answer:
The circumference of the circle is 28.26 m.
The area of the circle is 63.585
.
Step-by-step explanation:
To solve for the circumference of the circle, start by using the circumference formula of a circle, which is
. However, 3.14 will be used instead of
for this formula.
First, the radius of the circle needs to be found. To find the radius of the circle, divide the diameter by 2 because the radius equals half of the diameter. The radius is 9 m divided by 2, which equals 4.5 m.
Next, plug in the radius into the formula, and the formula will look like
. Then, solve the equation, and the answer will be 28.26 m.
To solve for the area of the circle, start by using the area formula of a circle, which is
. However, 3.14 will be used instead of
for this formula.
For the area, plug the radius into the formula, and the formula will look like
. Then, solve the equation, and the answer will be 63.585
.
Answer:
The price per ounce is $0.175.
Step-by-step explanation:
Given:
Number of ounces = 10
Price of 10 ounces = $1.75
We know that, from unitary method, price of a unit quantity is given as:

Here, the number of quantities correspond to the number of ounces.
Total price corresponds to the price of the 10 ounces which is $1.75.
Now, unit rate or price per ounce is given as:
Price per ounce = 
Price per ounce = $0.175
Therefore, the price per ounce is $0.175.
Answer: The answer is nine, because
2.5 x 10 = 25 m^2
1.5 x 10 = 15 m^2
2 x 10 = 20 m^2
0.5 x 1.5 x 2 = 1.5 m^2 (2 times)
Total = 63 m^2
So just fill in 63.
