Answer:
The answer is: 4,500,000 kilometers or in scientific notation: 4.5 x 10^6 kilometers.
Step-by-step explanation:
Multiply to get the answer:
300,000 * 15 =
4,500,000 km
In scientific notation: 4.5 x 10^6
Answer: 1106.13 (2 decimal places)
Step-by-step explanation:
To work out the area of this composite shape you would have to put the two semi circles together to form a circle and work out the area of the circle (they have provided the radius which is 11in), then work out the area of the rectangle separately.
The formula for the area of a circle is πr^2 (pi x radius squared).
So when you put the numbers in the formula the area is πx11^2=380.1327111
Then to work out the area of the rectangle you would do base x height.
The height of the rectangle is the same as the diameter of the circle (the diameter is double the radius of a circle) which is 22in.
To find the area of the rectangle you do 22x33=726
So then to find the area of the whole shape you would have to add the area of the circle and the rectangle together.
726+380.1327111=1106.13 (2 decimal places).
It's hard to type a table into these little boxes. Could you possibly draw the table on paper and share an image of the table here?
This is called a "contingency table" and is often associated with "dependent probability."
