Answer:
To the nearest hundredth : 628.32 
To the nearest whole number : 628
Step-by-step explanation:
The formula for the area of a circle is : 
To work out the area you would first need to work out the radius. You can do this by dividing the diameter of 40 cm by 2, this gives you 20 cm. This is because the radius is half of the diameter.
Now that we have worked out the radius, the next step would be to work out the area. You can do this by multiplying pi by the radius of 20 squared, this gives you 1256.64.
The final step is to work out the area of this semi-circle. You can do this by dividing the area of 1256.64 by 2, this gives you 628.32
. This is because a semi-circle is half of a circle.
1) Divide 40 by 2.

2) Multiply pi by 20 squared.

3) Divide 1256.64 by 2.

Answer:
3) 2.7
Step-by-step explanation:
The distance between two points
and
can be determined by:

Since the points are X(1, 2) and Y(6, 7). The distance between the two points is

the x value for the point located 1/3 the distance from X to Y,

The x value = 
Answer:
A.
Step-by-step explanation:
I decided to do a addition problem because based on the answer it couldn't be multiplication, subtraction, or division. Therefore, my problem would look like 15+9=24 birds in total.
Here are some probability scenarios.
- Flipping a coin and seeing if it is heads or tails.
- Thinking to yourself: "Is it going to rain or hail?"
- Spinning a spinner and seeing what color it lands on.
- Probability in winning the lottery.
- Having 5 pairs of black shoes and one pair of yellow shoes.
The probability of picking the yellow shoe is 1/5.
